We enjoyed our stay in the Blue House Appartment. Everything was according to the description on Air BnB. When you open the front door you step directly into the living room/ kitchen which is spacious, nicely furnished, modern and newly renovated as are the bedrooms. The apartment is well equipped with everything we needed.
The Blue House is located in a nice and quiet area, everything is nearby (metro station, supermarket, cozy bistros and restaurants in Montmartre...).
The check-in/welcome and check-out was handled by Guillaume from Bnb Sitter. Guillaume was a very friendly and helpful person. On our arrival, toilet paper and coffee tablets were missing. Guillaume took care immediately and the things where delivered on short notice.
Only we take off one star because there is no window to open to get some fresh air into the rooms. We had to open the front door for fresh air. In the basement (the bedrooms), there are no windows at all. There is kind of airconditioning, in the bathroom as well.
