Best of all is the location. A few steps to the streetcar that takes you downtown in less than 20 minutes. 2 grocery stores on the block, 3 excellent places to eat within the block. Pharmacy across the street.
I first had a single room which was very small and I found not too inviting. I switched to a double which had been remodeled and which was fine. I think the lighting could be improved. It had a small kitchen area where I cannot see fixing a meal, but ok to store snacks in the fridge or reheat something. All rooms seem to have an outside area, either a balcony or a little veranda. Breakfast buffet is nice. I particularly liked the receptionist, Angela, who is helpful and personable. The one who was on duty when I arrived not so much; she told me the room was not available until 3:00 and did not suggest storing my luggage until then . All other personnel are polite and helpful.
The rooms are cleaned by demand; days when they are not cleaned the hotel will donate 4 Euros to charity.
All in all, I would stay there again.
