Price (got it as a smart deal), location, cleanliness, friendly stuff. Wifi strength was very well, I used only one device, so couldn't say if connection of 2nd device was possible.
My overall stay was good, few personal concerns are mentioned in negative section.
No fridge, no minibar, no kettle in the room. No proper soap, plastic bottles with fluid named as liquid soap/shower gel. Shower tube could be bigger.
Breakfast looked overpriced for 13€, never tried breakfast to say something about selection and quality. Breakfast room was just in entrance hall, not in separate room. Used bakeries in town for breakfast.
Check out time in booking.com is indicated as 12pm, though information book in hotel says 11am.
