Location and inside were as stated in the add. However the host did not tell us on time that the door had this weird way to be locked, and we could not close it when we arrived. We tried to call her but she didn't answer. This made us panick a little bit. She did send us the instructions on how to lock the door a few minutes later and all was ok then, but this is really something she should have anticipated.
Other than that, the house is like 5mins on foot to the metro of Porte de Vanves and is perfect for a budget stay for a couple or for one person. The surrounding area is fine.
