The apartment and the experience was exactly what we expected.
Location:
It is located near two metro stations. You can find two big grocery stores in a 5-minute walk (Lidl and Monoprix). The apartment is appr. a 30-minute walk from center or a 15-minute ride on public transport.
The only thing is that during our stay (most likely will not be applicable to you, if you're reading at least a month after February 2022) we had a construction works on our street that made quite a lot of noise. They began working at around 7 am (no works on weekends) and it didn't help sleeping.
Building:
This is an old 4-store building. The entrance is old as well, with creaking wooden stairs. The apartment isn't good in terms on noise-cancelation, so we were able to hear our neighbors who went to work early in the morning or even had a small talk (once) when they met each other.
Amenities:
We had everything we needed for a comfortable stay. The apartment itself wasn't warm enough (early February), but we had electric heater so it wasn't an issue. A full-size bed was very comfortable to sleep in.
Host:
Christ was very friendly and answered all of our questions in a timely manner.
