Bertrand is an amazing host, friendly and communicative! He took us in last minute and we had a warm welcome chatting with him for the whole first evening. :)
Flat is super stylish and it's interesting to see Bertrands taste and soul in it. Bedroom is small but bed comfortable and you also have kitchen and big living room to hang out in. Location is good - very close to metro stations Simplon (4) and Jules Joffin (12). Close to Montmarte and Sacre Coeur.
Only downside was that it was cold! (end of October)
