This apartment is in a great location - a very cool section of Paris, right by Notre Damn, Le Seine, fun piano bars, tons of restaurants, close to classic places like Les Deux Maggots, Le Procope, and Cafe des Flores (check out all of them if you can!). I wish the apartment had better windows and lighting - it felt kinda dark and is on the ground floor. But at least you don't have any stairs to walk up with your luggage! I really appreciated the night life and the location of this apartment. I would definitely recommend staying here for short stays. Also it's extremely QUIET (nestled in a courtyard entrance) in a rather busy touristy neighborhood.
Gmt was amazing and a great host. He immediately responds to messages and helps you out for emergency situations. If you want to see the Latin Quarter, definitely stay here!
