Highly recommend Frederic's lovely flat in Montmartre. The flat is on the fourth floor and the location is wonderful: Anvers on line 2 is literally right at the door, and less than 5 minute walk is Barbes-Rochechouart on line 4; you can easily go anywhere in Paris from these two stations. Also night bus N01 stops at Anvers, very convenient if staying out late. Paris is actually quite small, and besides being right in front of the Sacre-Coeur, it is easy to walk from the flat to Gare du Nord for the RER B to the airport or TGV and Eurostar. There are three supermarkets, a big pharmacy, and a small bakery nearby, so staying in this cozy flat really makes you feel like a Parisian. Frederic is very friendly, and he keeps his flat clean and comfortable.
