My main complaint: I booked a wheelchair-accessible room. When I arrived, I found out that the room is actually a regular room (with a bathroom door so small even a tiny wheelchair couldn't fit through). When I inquired about this at the reception, a manager was incredulous, and didn't want to believe that a wheelchair couldn't go through the bathroom door.
After a little back and forth it turned out that the manager was in fact talking about a separate wheelchair-friendly bathroom -- one for each floor. Then it was my turn to be incredulous. First, the receptionist hadn't told me anything about this when I was checking in. How was I supposed to guess that in order to use a bathroom I was expected to go around a couple of corners in the hallway (some 20 meters from my room) and use a bathroom common for all wheelchair users on that floor?
Second, how could this be the case in a 4* hotel? This thing degraded the hotel for me to the level of a hostel.
Other than that, the hotel is OK. While not exactly pretty from the outside, it is nicely renovated and clean. The hotel restaurant offered good food (even though the waiter was quite inept -- he somehow managed to forget three items from five ordered; he did try to make up for these blunders by being very nice). The breakfast was very good indeed -- in addition to the usual fare of sausages, eggs, cheeses, and hams, it had a number of well-balanced salads (including warm ones), home-made spreads, pickled cheeses, etc.
I'd like to give a better rating, but the 'bathroom across the hall' arrangement did spoil the experience.
