As most people read about 3 lines of reviews this is going to be a bit of a mission I am afraid. And in truth I imagine how good this hotel is depends on many factors.
Let's start with the overwhelming positive - the bed. It was big & comfy. It did only come with 1 pillow but that is easily corrected.
The rest of the room.... well not so good. It's a bit cramped, not small per se but far from roomy. The desk is over large, takes up more space than is needed. The balcony - a plus in itself - is underutilised, in that there is a balcony but no furniture there. Bit pointless but hey.
The bathroom is fine, big enough overall I guess but the shower is the wrong shape. I will explain.... the shower itself is placed on the back wall, meaning that it is very narrow. I had imagined this was an issue for me, I am tall & broad, but my wife had the same issue. It's not a fatal flaw but it is a pain, if you turn wrong the shower will burn you/freeze you/vanish. Shame as it is a damn good shower.
Moving on..... the staff.... aside from the last day were really good. For the most part they managed to speak English, a relief as we struggle with Italian. They were helpful when required.
On to the breakfast.... basically its poor. Accepting that Covid has impacted this some what there is still a lack of variety & quality. Que to order, come back for toast & hope your eggs aren't cold. Hope that you are severed individually if you come as a couple - we never were but plenty of other guests managed it. Hit drinks are ordered at the table, sometimes & if they remember. And it is all pretty average. As a tip don't get it, walk 10 mins to the theatre Massimo & go to cafe Dami. Cheaper & better.
As I said it is odd but I would stay again, the location is unbeatable - great resturants near by & it is easy to walk to the old town.

My Husband booked this hotel for us to rest up after our lovely wedding, as it was stressful during these times. I emailed the Mercure ahead to see if they could offer us an upgrade or something nice for when we arrived. The Mercure replied positively. They booked our taxi from the airport and we were looking forward to our stay.

When we arrived, we were offered a room on the 3rd floor. There was no mention of this was the upgrade I was asking for, not even a congratulations.

Our room was a nice size and the bed was comfortable. There was a large balcony with no furniture, and when we first arrived, there was a man on our balcony, we think he was cleaning, and wanted to cut through into our room to leave. The WiFi can be a bit hit and miss, but mostly ok. The air con is noisy but it can be left on all day and turned off a night if needed. The shower temperature seems to be in the wrong place. There is a danger of knocking the lever with your arm, making you scold or freeze before you have realised you have knocked it. The bathroom floor is very slippery when wet. The room was clean, although housekeeping did forget to clean our room on one occasion.

The hotel is in a great location and Palermo has excellent street food. So I would strongly advise to not pay extra for breakfast at this hotel. It is far cheaper to go elsewhere. Due to social distancing, the food is now served to you, and you have to queue up for it. If I wanted scrambled eggs of on toast, I would have to queue for the eggs and for the staff to put the bread in to cook. I would then have to queue again to collect the toast and my eggs would be cold. Hot drinks are supposed to be offered to you once seated but we were sometimes missed. We gave up on breakfast we had paid for on a couple of occasions and went straight for the street food.

Because of the location I would stay here again, but I would do a few things differently. I would not pay for the breakfast, there are plenty of places you can eat at a much cheaper price. I would also bring a travel kettle and milk for the empty fridge in the room. That way I can have a hot drink every morning.

We really enjoyed our massive corner room with comfy sofa and generous bathroom. The staff at the hotel were really attentive and friendly, both before and during our stay, and they were always a pleasure to deal with.

We were a bit disappointed by breakfast however. We paid extra when we booked but the offering was only coffee and a selection of half a dozen pastries. I understand everyone is approaching the current situation a bit differently but this was the most minimalist offering of any of the 3 Mercure properties we stayed with in Italy. Still a nice way to start the day but I wouldn’t recommend for big eaters
