Martin was in constant contact with us, from confirming our arrival with instructions to meet his cleaning lady at the apartment for the key, to talking us through how to open the door (for best results, you should give the door a little tug towards you as you turn the key all the way to the right!), to confirming our departure. We couldn't have asked for a better host. The apartment itself was very nice, certainly for the rate, if a little tight in the kitchen and bathroom. And be prepared to walk up 5 flights of stairs with all your stuff! Proximity to Pere Lachaise Metro is great, there are a few velib stations around, and a carrefour right across the street.
