Reliability, cleanliness and calm.
This apartment is in a great location. On the smaller side, but who cares when you're in Paris. We stayed here with 2 adults and two young kids, and it worked out just great. Easy access to public transportation, and lots of restaurants and shops within easy walking distance. The apartment is in a nice building, off a quiet street. Right now there's some construction going on, so it was noisy in the morning, but typically this would be about as quiet a place as you can get, as it's off a cul de sac side street. Mourad is an awesome host. Very communicative and made things super easy at check in / check out.
