The apartment is small but charming and has everything you need. The location is perfect for travellers looking to be in the middle of action, there are way to many options around to eat, drink and party and you're also close to most other interesting locations around Paris. There's also a metro station like 4 minutes away walking.
But If you're looking to rest and relax, this might not be the best option for you because even though the apartment is on a third floor and the window's seem to be double glazed, the noise at night is still a bit too much, specially in the bedroom. This is not the host's fault of course, not much they can do about it and it depends on what travellers are looking for in their stay too.
