Really cool place. The patio is amazing and the apartment is very nicely decorated.
If you're looking to go to bed early though this place is not really for you (in the summer time at least). The bedroom is street facing and because it is a small street EVERYTHING echoes. Additionally, the walls are pretty thin in the apartment itself so you can really here the neighbors walking around.
That said, the location is great. Super close to Republique and lively delicious restaurants makes this place wonderful for exploring Paris.
