Xavier's location was perfect for us. It's conveniently Located within minutes of the metro, right next to a mall, and tons of great restaurants and bars to try, also within minutes walk from Norte dame and St Chappell. But he's located on a pedestrian street so It gets a little noisy in the evening but with the windows close It's not too bad. There's a great view from his apartment which over looks the street. Building seemed a little old which is typical for Paris but apartement was updated. There are lots of stairs up to his place so be prepared to carry your heavy luggage. I would recommend staying here if you dont mind walking around and exploring Paris, there's lots to see!
