Stayed there for 4 nights,overall expression is fantastic. The staff is really great, especially big thanks to Pantea at the Front Desk, who demonstrated exellent customer service as well as professionalism, Sunil from concierge who was always helpfull and Beebob with Eddie from Makan restaurant-they were real stars!
The location is very convinient if you want to explore KL, the Petronas is only 10 min walk and Bukit Bintang is only 20 min by foot.
The rooms are well equiped and comfortable.
The Breakfast were the best I ever had in other hotels. Big thanks to all the Chefs!
The only negative thing is lack of information at the check in and hassle with the deposit thing. The first time I came to check in,I had only debit card and the trainee guy nearly refused to check us in,even thought i agreeded to pay for the rooms up-front.As i work at the FO for Hilton myself, i asked him to put stop-charge on our rooms,what he did. I could not understand why he could not advise that himself.
The second time i came to check in after our trip to Langkawi,i experienced the same problem but it was sorted out by Pantea.
Would definetely come back!

Have stayed in this hotel 4 times. This review is for the recent stay for 2 nights 3.2.12 to 5.2.12 in the Executive Suite.
Check-in as usual is a bit troublesome - having to go to 1st floor for the lobby. For executive floors, you can actually check in and out at the Executive lounge on Floor 34. For parking, you have to pay a flat rate of RM10 per night. Check with the staff on the parking rates because sometimes it can be cheaper not to pay through the hotel.
Cookies as usual nice and warm but getting a bit impersonal. During my first stay, the check-in attendants had great big smiles while handing over the cookies. Cookies are still around but the smiles have faded.
The Executive suite is big for its price. 60+m2 and comes with 2 LCD TVs so my kids need not fight for the control. Has a basin so you could wash up easily if you do some light cooking but we never tried. Bathroom is big enough with ample shower space separated from the bath-tub. They also provide Crabtree & Evelyn toiletry. Water pressure has improved.
In room dining was ok, I find the price reasonable but for those who prefer their standard fast-food, McDonald's is just across the road and you can even call for Domino's pizza delivery.
The Makan Kitchen is huge and variety is very good for meals but noise level can be high. More recently we have our breakfast at the lounge where you get equally good stuff and the variety is good enough. The lounge serves alcohol in the evenings up to 7.30 so it is a nice way of winding down. For those not from KL, the twin tower view from the lounge is also nice. It was also a pleasure seeing the familiar and friendly faces of Sue and Malar at the lounge.
The hotel also provides child-proofing services and child-care services. Handy if you decide to use their shuttle to drop by KLCC for shopping. Finally, they have a salt-water swimming pool, something unique.

Having spent 2 nights here, I was not enamoured by the Doubletree KL. It's a brand new property so as you can imagine it is spotlessly clean and the rooms are what you would expect from a Hilton location.

Check-In was a mystifying experience, there can be anything up to 12 agents occupying the front desk and most seem to be on training and struggle with even the most basic of tasks or questions. I was not impressed at being hit for a RM1000 Visa authorisation for a room that was full prepaid, excessive considering we have stayed in better hotels who have sought half that amount. The room keys were erratic and sometimes stopped working of their own accord, twice we were locked out and had to return to reception for reprogramming. No explanation, nothing.

The Exec Lounge is a miss unfortunately, save for the majestic view of the Petronas Towers from the small balcony. The staff linger around the supposedly complimentary food & drinks, really offputting and in no way relaxing or discrete whatsoever. And again, most wearing a Training Badge (I would lay the blame at whoever was supposed to be doing the training rather than the staff who done nothing wrong just didn't know what they were supposed to be doing). The Doubletree could do with sending their staff over to the Hilton KL for training, it really isn't that hard to be fair.

I should mention that there was some kind of works happening outside the hotel so the walkway from the metro station was obsctructed and unfinished. There was no elevator so we had to carry 2 full suitcases up a large flight of stairs and down again the other side, not the most pleasant way to arrive when there are homeless folks sleeping rough impeding your entrance. Navigating the traffic junction was nearly worse, no coherent Walk/Don't Walk system so you just made a run for it half the time hoping you judged the lights correctly(!). Poor planning from both the powers that be in KL and/or the Doubletree KL. It's a total safety hazard to pedestrians.

If the Doubletree sorted out it's teething issues, it would be a fine hotel with all the trimmings and I'm sure they will get there eventually, but not without a reality check or two and perhaps reviews like these might speed them up a little.

The hotel does have a nice pool alongside an Italian restaurant which is adjacent to the on site gym and spa facilities. Gym, Sauna and Steam Room are complimentary but obviously the Spa is a la carte. We did sample treatments and found it to be of a very high standard, they could do a little more with the outside area leading up to the Spa Treatment rooms to make it feel less like a hospital visit. But zero complaints about the treatments themselves (apart from the western price card!).

The Buffet Breakfast was plentiful and lots of choice but was crazy busy, we found the Exec Lounge to be a much more relaxed affair for Breakfast albeit smaller selection (they did have omelettes etc. on order which was nice).

So all in all I'd say the Doubletree could remain in your consideration if you need clean and comfortable accomodation in KL, it has some service issues but if you look past these then you will have a fine stay here. In direct comparison to the Hilton KL at Sentral Station, the Hilton is far superior and would be my preferred property for any future visits to Kuala Lumpur.

Your mileage may vary!

Perfectly good 4 star hotel with modern, clean rooms, great pool area and conveniently located in central KL close to all the attractions. It is housed in what can only be described as a high end shopping mall so does take a while to get to reception. Other than that no complaints but maybe slightly lacking in soul and atmosphere... good for business.
