We stayed 5 nights at this apartment (which is actually a basement in a house). The best part of this entire booking was the check-in, Isabelle was warm and friendly and very responsive so we didn't worry.
We were at the apartment in the thick of winter and despite the large expanse of space, the area was only equipped with 2 (rather weak) heaters, which means we were basically freezing all the time. It was quite difficult to bear and we took to spending as much time outside as possible, only returning to shower and sleep.
There were also safety and privacy concerns which were not stated. Apart from the shared main door (still ok), there was a door in the toilet which connected to some sort of basement room in the owner's house, which they had full access to. This was a transparent door covered loosely with a cloth on the owner's side, which also meant that as two girls, we lived in fear of someone peeking in whenever we showered or slept. The toilet also has transparent wall, btw.
