Gilles was a fantastic host. Communication was fantastic and he met us at the apartment when we arrived to explain everything to us and give us some tips about the neighborhood.
The apartment is small, as is typical for Paris, but incredibly well appointed. It's a really pleasant place to rest after a long day exploring. We particularly enjoyed that the apartment has a Nespresso machine for making coffee before leaving the flat. Hot water was plentiful and the water pressure was great.
The apartment is a 5th floor walk up, so that was a bit tough with all of our luggage, but after the initial climb it wasn't too bad. Additionally the bed is a pull out couch with a thin-ish mattress. I didn't mind it but my girlfriend had a hard time getting comfortable some nights.
Overall I would highly recommend Gilles as a host as well as this apartment. I would definitely stay here again should I visit Paris in the future.
