Guillaume's apt is fantastic! The location is absolutely unbeatable - right in the middle of Le Marais. Great restaurants, people watching, little shops, close to major subway lines... etc etc! It is very cozy and quiet. Also, Guillaume couldn't have been more hospitable. He was accessible 100% of the time if needed, and willing to help any way possible to make my stay as effortless as possible. I stayed here for 18 nights and I will definitely stay again. Thank you Guillaume once again for the terrific apt and for being such an outstanding host.
