Great location in a very fancy neighborhood. Ruby answered quickly to our enquiries before/during/after our stay.
However, there is a clear sign in all elevators that AirBNB is illegal in the residence, it's quite awkward... The host mentioned that it was fine as she owns several appartment in the building. Quite shady.
Overall, the appartment is nice even though it needs refreshing (crumbling ceiling with humidity in the bathroom, broken floor in main entrance). The equipments work fine. Lots of storage area.
Note that the high ceiling is only in the living room. Second floor roof is about 1.80m high so not suitable for tall people.
Isolation between the two floors is poor.
We were four in the appartment which was very comfortable and gave us a lot of space. I think more than 5 people would be too much as there are only 2 small bathrooms.
