Frédéric was very helpful and accommodating. Our plane was delayed and we were unable to contact him until we landed, but he was really flexible with us and didn't mind us checking in very late. The apartment is really nice, clean and well furnished, and probably most important for short stays, close to the metro and walkable to the main attractions of the city. There is only one bathroom and toilet, and you have to go through the main bedroom to get to it so this is worth noting for business travellers - but it really didn't cause a problem. Really great experience.
