Positive: Audrey was very easy to communicate with and was helpful when we requested more towels and linens. She was also flexible with the check out time.
The location is very central and there is easy access to most locations in Paris. The metro stop is one minute away.
Negative: There is no ventilation in this apartment. We arrived during a heat wave and the place was unbearably hot. It does not have air conditioning (like most places in Paris so we were not surprised by that) but the apartment could use a couple of fans to move the air around. It is on the first floor of a very busy street so keeping the windows open makes the place very loud. We had to wear earplugs while sleeping to drown out the street noise and the thumping bass coming up from the restaurant below.
It is a very old building with old pipes. As such, every morning the bathroom smelled like rotten pipes, it seemed to get better later in the day.
The amenities are very sparse. The basics are supplied (one towels for each of us and one kitchen towel) but nothing more.
