The room I stayed in doesn't look like any of the pictures displayed; unfortunately, I forgot to take some pics to upload them here. There was a small desk very close to the bed, so close in fact that there was no chair and I sat on the bed to work on my laptop.
The toilet was also very, very small. I'm 5'9" (1m75) tall and thin, and I almost touched the walls on both sides, plus my knees touched the wall in front of me when I sat. Bathroom (shower and faucet) was small but OK.
I made the reservation for a single room. There was a full-sized bed, but with only twin-sized sheets and 1 pillow.
The room was left uncleaned 2 days during my 7 nights stay, even though one of those 2 days the "please clean the room" sign was on the door handle.
Breakfast buffet was OK, but far from memorable, in a place that looked like an old school cafeteria.
Finally, to get to my room, I had to go out of the building from behind, where the entrance of the parking lot is (as well as a car rental company) and then enter the building on the side (the one on the right side in the main picture). Not quite high-class. I it was my first trip to Prague, I'd think I shouldn't expect more for a (more or less) cheap hotel, but I've stayed in other hotels that were in the same price range and were a lot nicer (unfortunately, they were all booked when I planned this trip).
