Heating was supposed to be turned on in October, but was not fully functional.
Once late at night (3 people) and once early in the morning (1 person) came to my room suddenly without notice (door was opened with a card key). I did not let them into my room. I checked with the hotel and they said that the staff went to my room to check the heating, which is only done late at night, but it was very scary.
Clean, good amenities, wonderful shower with big towels. Buffet is very good: high quality, wide selection of dishes. Gym is clean and well apportioned.
