This is a cute, nicely fitted and decorated flat in a nice area, neither rough nor too touristy. It feels like 'real' Paris. Given the liveliness of the area, the flat is surprisingly quiet and we loved the tranquil, beautifully planted courtyard below. It was easy to get to any other area from the nearby metros and there's a nice big Monoprix just around the corner for groceries.
NB. If you need to use all the beds, make sure you stipulate that when you book or you might find yourself without sheets for the single beds as we did.
