Beautiful apartment, right off Rue Montorgeuil. The bedrooms and bath are large, and the kitchen well equipped. The team that manages it is well organized and responsive to questions about the apartment. That said, they are truly inflexible about check-in / check out times. Everyone on Airbnb says that they are not flexible but usually, if there is no one in the apt directly before or after, they try to accommodate. When I asked about a possible early check in, they did not even respond, but resent the boiler plate with the "PS" about no flexibility.
I was already in Paris and taking this apartment to share with a friend who was just arriving. I could take it a day early so she could come directly, but if you're getting off a long flight and jet-lagged, take it into consideration.
There is also a bar downstairs, and the revelers are loud late at night – and this was November. I was fine, but the other guests had a hard time sleeping.
