Pierre's apartment is a fantastic base for exploring Paris. Close to a heap of public transport options, it is easy to get anywhere. Montmartre has a great range of shopping and eating options within an easy walking distance, including the most wonderful boulangerie right across the road from the apartment.
The apartment is clean, comfortable and incredibly quiet given its location. And of course there is that great view of the Sacre-Coeur!
Pierre is a lovely host - easy to communicate with and thoughtful for the comfort of his guests.
I highly recommend Pierre's place. I would love to return.
