The Royal Park Hotel is an excellent hotel for people travelling for business or pleasure. The staff is all very outstanding and service oriented. English is not a problem at this hotel. As far as I'm concerned, this hotel service is on par or exceeds that of other 5 star hotels in Japan that are much more expensive. The restaurants that I tried, the Japanese sushi in the basement and the Chinese restaurant are both again excellent in quality and service. To top it all off, the hotel is right above the Suitengumae subway station and the TCAT bus terminal with direct bus access to Haneda and Narita airports. I will stay there again. In fact I have already booked my next stay starting 4March.

I'm becoming a regular.. attracted by the location.. just steps away from TCAT..Tokyo City Air Terminal.. very convenient connections to Narita Airport. Staff is first class, friendly and helpful. Big discounts are available if you look hard. For example, the hotel passes out 30% discount coupons for exec flors after a few stays. Corporate discounts can be even better.
-Executive floor is nice, but nothing special.
-Good fitness & pool area.
-Internet fee is about $12 US, but free on executive floors.
-Great riverside walk/jogging along the Sumida River.. goes for miles and miles
-Subway access in the basement
-Convenience store (7-11) across the street
A solid business hotel...

Staff friendly and helpful, restaurants a little pricey, across the street from the TCAT so easy connection to Narital and Haneda. The rooms very comfortable. On second visit was upgraded to corner suite- all I can say is WOW.

Stayed here for 2 nights on business in Jan 2012. Handy for airport via TCAT bus (directly under the hotel). Arrived around 11am after an overnight flight and had to wait for 90 mins for my room - was offered a business class upgrade for Y3000 which included breakfast but declined as I usually dont eat it. Worth buying the upgrade if you do - it also includes internet so represents a saving. As always in Japan the concierge is very helpful in planning travel to meetings and even a trip to the Sumo. Hotel can be expensive but some of the discount sites can offer reasonable deals.
