The studio was really central- only 5min walk from Gare de l' Est - 20 min from Les Halles. There are also many bars and restaurants around the place. The place itself was big enough for 1 or 2 person. The bathroom was quite clean. Sometimes it could be really loud because of the metro, which is normal for a big city as Paris.
I have never met Enguerran- but I met his friend Pierre. Thanks for your hospitality and your help. I love to come back sometimes! Thanks for having me there!!!
