Room was clean and fixtures were in good condition.
Strangely, the "double bed" and "two single beds" are actually the same thing, they just push them together or apart respectively. When I arrived my room was in "double bed" configuration. Then after the first day it got changed into "two single beds" configuration. When I mentioned that I preferred the double bed, I was informed that that costs more.
The speed of the WiFi Internet was abysmal, it took close to a half hour just to download email attachments.
There were some weird banging noises coming from above (no, not that kind of banging, more like somebody dropping marbles on the concrete floor at all hours of the night), I'm not sure what that was about or how much the hotel could do about it. One night there was also the smell of cigarette smoke coming through the ventilation. I assume that this was one of me neighbors violating the no-smoking policy.
Otherwise, the stay was quite nice. The breakfast option (10€) is a good bet, as the selection is decent and there's not much else to eat in the morning in that neighborhood.
Staff was very polite and helpful.
Overall, would use again.
