Overall it's OK, not a disaster but not great. Quite a lot of the power sockets didn't work (including an entire bedroom) - it didn't really matter as we weren't there much but would annoy some. Plus there was very loud building work ongoing from 8.30am every morning, which we hadn't been warned about. Walls were very thin - noise from other apartments woke us up most nights. Towel hooks were stuck on with glue, and so fell off if you put a towel on them!
The host (it was actually an employee as it looks as if this was one of a number of flats under the same management) wasn't there to meet us as arranged (we'd communicated at the airport via WhatsApp as agreed) and we ended up on the street for 30 minutes with elderly relatives - not ideal. It would have been better to be honest and say that he had to let someone else in elsewhere, so we could have waited in comfort at a cafe. The cleaners also tried to get in before our check out time of 10 a.m. at the end of our trip.
Positives - nice balcony, bright kitchen area, spacious, very near a metro.
