Staying at Carmen’s place was a good experience overall. The place is well-located (close to everywhere by bus and with Nice restaurants nearby) and it has a great rooftop. The place was clean: we noticed 2 cockroaches in the apartment one evening, and Carmen’s response was very professional and the cockroaches never returned.
One a bit problematic thing is the ventilation of the apartment. It gets very hot during the day and the air conditioning works only in the kitchen. In the bedroom, you only get fans which was not enough. Moreover, you need to pay additional small fee for AC. Maybe it was written in the description of the apartment but we missed it.
