We had a pleasant stay at this apartment. It is ideally situated just across the street from a Metro station, making access to anywhere in Paris much simpler.
It is quite small, but enough for a couple on a short stay. Also, while the outdoor courtyard is nice and semi-private, your view is only the concrete walls of the inside of the apartment complex, so you don't really feel outside.
The apartment had most of the amenities we would like, with good Wifi.
