Antoine's apartment is clean and lovely, with excellent proximity to public transportation and the beautiful streets of Montmartre. If you are looking for an authentic Parisian stay, this is the neighborhood for you. The bed is very comfortable as well. We had a couple of problems with hot water access and the lights in the bathroom, and frequently needed to flip a switch in the circuit breaker cabinet to turn them on.
Unfortunately, Antoine was a bit difficult to get in contact with, we sent multiple messages letting him know when we would arrive before hearing back. He had to send a friend to let us in, and we had trouble reaching the friend as well. Like others, we would suggest a lock box or other way to exchange the key.
Overall, lovely experience in Paris. Thanks Antoine!
