We booked a room on the first floor, because we read some reviews, one of the rooms on the ground floor was in a corner next to the breakfast area. (see other reviews over here)
when we arrived they gave us this room...but when we asked if something went wrong, we were replaced to another room on the first floor the next morning.
We also got an upgrade I assume, so solved perfectly.
Our stay was great, but we would not recommend to book room "0".
This room is moist, has no windows, and is directly to the breakfast room. so when someone takes a breakfast early, you will also be woken up early. and when you get out of the room, everyone faces you directly...feels like you have no privacy.
all the other rooms seem to be perfect. It is a nice, old (the facilities are modern :), don't worry), cosy hotel with really nice details. The staff was really nice and helpful.
