Great location - walking distance to Château-Landon Metro, Gare de l'Est and Gare du Nord. The hallway on the 2nd floor and elevator was quite dark and looks old, but the unit itself is great. We were informed that there are plumbing issues but we didn't encounter any problems.
Sylvain responds quickly to my messages, and has been such a gracious host. He allowed us to check in early and even gave us a surprise treat to welcome us to Paris. Thank you very much!
