Me and my boyfriend spend wonderful time in Paris and had great accomodation in Sabah and Alex flat. They was really friendly and helpful always ready to explain or translate sth for us. Sisi didn't bite us and she was always happy when we come back to home :)
Also Sabah and Alex friends were very polite and kind for us.
Flat was clean and spacious, bed very comfortable. Localization was very good, near to metro station and not to far from city center. In surrounding you can find cheap shops, park and some interesting places (like Père Lachaise Cementary). But this flat is not for someone who want to have big privacy (room is shared).
We recomended this places with all responsibility!
