This is a terrific place in a wonderful part of the Marais. Very comfortable & clean. Like other travelers have said here, the stairs are the only possible issue - narrow, winding and steep. Also, be aware that there is no sitting area. I couldn't really tell that from the pictures - bedrooms, bath and kitchen area only.
Louise is a very responsive host as well - answering questions, setting us up with luggage storage for our arrival earlier than check in, etc. She responded immediately when a leg of the bed broke and had someone come to fix it before we returned from being out and about.
Be sure to check out the restaurant just downstairs - Restaurant Extraordinaire where the food is natural/organic (and delicious) and the servers/cooks/hostess have Downs Syndrome (Trisomie-18). It was a fabulous dining experience.
