I stayed in Quentin's apartment for a few days with a friend. Overall it was a really good experience! Quentin was very nice and the apartment is really at the heart of Paris, close to the Louvre, right next to Palais Royal and to three metro stations. Walking distance also to the opera. Downsides include the stairs to get to the apartment (so many of them hahaha), the toilet (it doesn't work very well) and the shower (doesn't stay in the wall). However, for he price and location this is still a very good deal! Would definitely recommend it.
