Two things stopped me from giving it full marks and those were: no a\c and no comfy chairs.
When I arrived at the hotel and met with one of the receptionists, Vavara, she was very very helpful. Nothing was too much for her, in fact, I relied on the reception staff quite a lot at first on where to get trams, metros etc.
The first night I had to go to the local Potraviny to pick up some milk etc. I got lost and went back to reception where she showed me how to get out of the back of the hotel (which was a legitimate entrance/exit), and where the shop was. To me, this was awesome as I have mobility issues so to get into the hotel via the back way made my life so much more better.
One day I was in a lot of pain and stayed at the hotel for most of the day, there were 2 dining chairs and a small table for eating. This was great for breakfast, but couldn't sit on the chairs for more than 30/45 minutes as they were not very comfortable. I ended up having to lie/sit on the bed, which wasn't too comfortable after a while. Hence me saying no comfy chairs.
The Hotel is a short walk to/from the tram stop. For people minus walking problems, it would only take 3 mins to get there. I could get straight into Prague via the tram. The metro was 2 stops down the line on the tram.
All in all a fantastic break and a great place to stay for the price.
