I stayed for a month in Helene's apartment. In summary, fantastic location, great host, great apartment, great stay in Paris.
In detail:
Host is superbly responsive, responds in minutes. Check-in was smooth, Helene was waiting for us and it could not have been any easier.
The apartment is gorgeous. Very sunny, morning sun in the living room, afternoon sun in the kitchen and the main bedroom. Very clean, which is especially important these days. Everything works. Beautiful balcony, with a couple of chairs and a view of the Eiffel Tower. Beautiful spot for morning coffee or an apero. Large living room, large bedroom, hotel-quality linens, fully equipped kitchen (even a small mixer and fruit juicer), washer, dryer. Fast internet. Everything one may need for a pleasant stay.
Location: on a quiet street but right next to Avenue Victor Hugo - which makes it close to several metro stations, bus lines and the monuments. Wonderful location.
In summary - a really great AirBnb experience with a great host. Thank you Helene!
