It's a solid option for short stays if you don't have to worry about laundry. The nearest laundromat is a little tricky to reach (15 mins or so by tram) and wasn't the most reliable.
The neighbourhood is mostly silent although there was some action at late hours during some days. So consider sleeping with ear plugs to play it safe.
The fact that the apartment is in the lowest level of the building is a big bonus during the hot period of the year. Even though there's no AC, I had no issues with temperature (normally a problem) and it was nice and cool whole stay.
Overall a good choice if you take these caveats into account. The sweet spot would be a short stay and the hosts seemed responsive enough. No problems with communication whatsoever.
