We (3 adults) stayed for 3 nights and had overall a good time.
First of all the location is really great (at least for our purposes). Bus/Metro around the corner and bakeries, bars and supermarkets also really close.
The appartment itself was big enough for us, but there was an extremly loud ventilation system (or something similar) on the building next to ours, which made it impossible to sleep with an open window and without earplugs. So I'd recommend to bring earplugs!
Unfortunately, the dishes weren't properly cleaned (big no-go for me personally) and no pot cloths, which meant we couldn't touch the hot pots after cooking.
Overall I can recommend the appartment, except for the semi-clean dishes.
