We had a wonderful stay in Marc's lovely Montmartre apartment! The apartment was clean, quiet and well-equipped with all we needed for our stay. Marc and Me. Lauro were very helpful and friendly.
In response to an earlier review, I would instead suggest using the Anvers metro station when you arrive if you have much luggage. The Abesses metro station has 100+ spiral stairs to climb. From the top of the Abesses station it looked like there might be an elevator, but we could not find one at the bottom. Either station is fine as long as you do not have much luggage to carry.
We were extremely pleased with our stay at Marc's apartment and would definitely stay there again. Thanks Marc!
