We stayed at Jonathan's for 3 weeks and we were thrilled with our visit!
THE SPACE: The apartment is the perfect size for 2 people, and it feels very clean and homey. Overall, the space felt even nicer than we were expecting from the pictures. It does sit on a large street (Rue Claude Bernard) which can be noisy but as soon as you close the windows you can barely hear a thing -- very impressive sound insulation! We didn't use the kitchen much since we ate out often -- it's small, but it contained everything we needed to make occasional tea and toast and it even has a dishwasher which was convenient.
THE HOST: Jonathan was the perfect host, he greeted us at checkin and even called to make dinner reservations for me one night at a great place he recommended. Jonathan's mom checked us out and was very sweet as well.
THE LOCATION: We enjoyed having Rue Mouffetard so close by as well -- it's filled with French students, locals and tourists, and it makes for an interesting mix! The food and pastries we got at various spots on Mouffetard were mostly high quality. We particularly recommend Saigon Mouffetard and Bonjour Vietnam for outstanding Vietnamese food. There is also a plaza full of outdoor cafes a little further down Mouffetard (near Saigon Mouffetard) which is a fun place to grab a late night drink.
NOTE: Be sure to thoroughly read the description of the property. It notes that there is a weekly cleaning fee that is not included in the Airbnb total but that you must instead leave in cash at the end of the visit.
