My husband and I stayed here for 4 nights on our honeymoon. The place was exactly as described: gorgeous terrace with spectacular views, fully functional kitchen (which we didn't use), nice living room and bedroom. It was small but definitely had plenty of room for the two of us. We loved how many windows there were! We also found all of Martine's Paris guidebooks very useful, as well as the iron and ironing board.
Martine was very accommodating of our early arrival time, and allowed us to store our baggage for a few hours before we officially checked in. The building was very secure and very close to public transit. For walkers, the apartment is only about a 50 minute walk to the downtown/the Seine, which we did a couple times. There are many nice restaurants close by-- we specifically liked those on Rue des Martyrs. The area of Montmartre was a bit too touristy for us (specifically around the Sacre Coeur), so we spent most of our time farther south in neighborhoods like Marais, Bastille, the 10th arr, and the Latin quarter. We also really loved St. Germaine on the left bank.
Thanks for a wonderful stay, Martine!!
