The apartment is bare bones: not even fitted sheets nor liners on the mattresses. There is no coffee maker, and the scarcity of decor plus lack of any historic charm makes one feel like it's a prison cell. Also, the washer is outside, through a tiny door: I don't know how get through there carrying a load laundry, even if there were a basket (which there isn't).
The location is very good, but the stairs inside are very steep.
Overall, it's fine for one night or if you need the extra beds/showers for a larger group, but any longer and I'd be very uncomfortable.
