There is no better location for an Air BnB in Paris. This flat is literally at the foot of Sacre Coeur. Lots of cute restaurants very nearby -- including Pink Flamingo Pizza (which seems silly to eat in france, but it's so good for a night in!).
The shower is fabulous, but beware if more than one person wants to shower each morning -- limit your bathing to maximum 5 minutes. Hot water disappears very quickly.
The apartment is very cozy with a well equipped kitchen - everything you need for a relaxing stay in Paris.
My one complaint is the bed situation. My friend and I stayed together, but didn't want to share a bed. The pullout couch is VERY uncomfortable and really not good for sleeping at all. If you are a couple and are sleeping together, beware that 'intimate times' might be a tad uncomfortable -- the mattress is super thin and hard.

Basically this apartment is perfect other than the bed situation. If Sebastiano upgraded the bed and the couch I would stay here a thousand times over.

Sebastiano is wonderful for communication, too. Great host!
