We stayed in early July 2017 in Isabelle's apartment. We really liked the place, it's well-ventilated and big, but we felt it should be announced to a maximum of 4-people, not 5, which was our case. The sofa-bed wasn't that comfortable for 2 people, so we had to improvise. The proximity of metro stations, markets and restaurants was a very positive aspect.
We also felt a little uncomfortable to the fact that there was a lot of personal stuff in the apartment, like kid's trophies and memorabilia, and were afraid to break anything. However, everything went well in the end.
Isabelle wasn't there to the check-in and check-out, but Mrs Da Cuna was extremely helpful with all our needs during the stay.
