I stayed at Guillaume's place for over 2 weeks and it was overall a very positive experience. The studio is charming and located in one of Paris' best area, lively, authentic and full of good gems. The métro is 3 mins away and the flat is closed to main roads which makes it easy to hop in and out of a cab too. Guillaume was very responsive and even though I didn't met him he was very considerate and made sure everything was going well for me.
