Xavier's place is without a doubt one of the best places I've stayed at in Paris. In short, his staff, the location, and room made my second time in Paris all the more better. I highly recommend staying here, for you will be so close to everything—everything essential to this awesome city is in walking distance, including the Metro station. My next visit to Paris will, hopefully, be at Xavier's. Also, Tom, a staff member, was awesome and very kind!
Cheers, friends.
