Just fantastic all around! If you dont have a strong preference for one arrondissement over the next, you cant do better than this. Wonderful, informative hosts. Easy walking distance to Montmartre, opera, Marais and RER. The pull out couch was quite comfortable, everything was easy and straightforward to use. I do wish I'd paid better attention to it being on the ground floor, as a woman alone I would have felt uneasy. Together with others it did not bother me. I would stay there again (with friends). Enjoy!
