The hotel is a well lit, clean and organized space. Some people may have an issue because the elevator stops between floors, so you still have to brave some stairs, but it was fine for us. Room was clean, bathroom was good. Shower had good pressure. I thought that the big towel was still not big per my own personal standards, but it was okay.
We were in the room during regular spring weather, so there was no need to turn on the AC, but the room had it. The remote for the AC costs extra per day if you need it though.
Breakfast was good, selection was normal and standard for everyone's needs. Coffee machine was used constantly by me and other guests, that was very nice. Staff in the breakfast room was really super attentive, acting immediately if someone needed assistance or if the table had to be cleared. Can't remember when was the last time I have seen staff so attentive, that was great.
We didn't really have bad experience, except something that was probably cultural for this part of the continent. When something happens that's not planned, Czech people tend to accuse the guest first, then investigate. Our check in for two guests was a couple of days apart, and that broke the staff - they were immediately thinking about charging us extra for the room, breakfast and everything imaginable, just because staff did not share messages about the situation. Where we come from it's nothing unusual, so we didn't take it too serious. That's why we gave it 4 stars.
