We stayed at Adrien’s place for 1 week and everything was perfect. The apartment is very clean, cozy and well equipped (kitchen amenities, WiFi, stereo w. Bluetooth, TV, heating). There are several good restaurants nearby and the location is ideal for sightseeing - ~10-15 min walk to the Arc de Triomphe and Champs-Elysées, with the Pereire metro ~5 mins away. This unit is on the 6th floor and there is no elevator, which wasn’t a problem for us, but is worth noting.
In addition, Adrien is a lovely host - extremely accommodating (he let us check out late in the afternoon) and responsive. I highly recommend this place and would happily stay here again the next time I visit Paris!
