Spent a week with my girlfriend at Ada's place during a summer holiday. The room was ok, but not super clean. Also there's no lock on the room door and the window opens to the balcony wich everyone in the house has full access to. The shared spaces are very tight and the kitchen can hardly be used by more than one person per time. The kitchen also wasn't very tidy (we found encrusted coffe on the small cups) so we decided not to use it. The bathroom was good, even if small, but the shower holder was broken so we had to hold it ourselves. We've never known who else stopped by as guest.
The position of the house is great, having a metro stop really close and a few valenbisi racks nearby.
All in all it's probably a decent place to stop by if you're only staying for 1-2 days, otherwise I'd recommend looking for something else.
