We were disappointed and to be honest we didn't stay at the flat.
First, when we arrived, it was not clear about the situation of the flat. The meeting place is at their rental office to sign papers. We were not informed about this.
Also note that there are several appartements. So the photos showed on the website are not really relevant for the flat you'd like, as the host decides for you which one is available.
Then, there was not elevator. I didn't notice this point when I've booked this reservation but you have to keep in mind that it's possible. And as we had a baby and a stroller, it was not convenient for us at all.
Finally, a quick and bad experience. We left the same day.
