Travelled as a couple. There was plenty of room. We really liked the interior and the slanting floor was an interesting feature. We are non-demanding travellers, so the small details that others might find as negative were not a problem for us. (No elevator, relatively bare kitchen, only a couple of coat hangers, no A/C, etc). We were just fine with the fan and open windows. There was some passing noise at night on the weekend, but weekday nights were quiet. The location is central, but still calm in our experience. We were very happy that we chose this place and would definitely come again. Be sure to send a message before arrival as the reception is not open in the evenings. We forgot to do this, so that was our mistake. But we quicky received the needed check-in information after we sent a message.
The only real negative for me was the lack of sorting/recycling waste. We are very conscious about this when we travel.
