Overall good experience.
The apartment is located on very top part of the building and has a very beautiful light inside throughout the day. Huge windows overlooking the parisian roofs and white painted walls make incredible atmosphere inside the loft. Be warned though, it gets very hot inside as soon as the sun hits the windows (we were staying during the heat peak in july, it was ok with ventilator, but far from comfortable if you plan to work from home during the day... in colder month should be perfect I guess).
Kitchen had all needed for a simple breakfast.
Communication with Alex was smooth and he responded very quickly when it was needed.
