This is a very small single room on the ground floor on the courtyard in a good location, but expect sawing noises from woodworking business in the court during daytime hours. No real kitchen (microwave, minifridge, no cooktop, no pots), unfortunate given the proximity of the Richard Lenoir marché. The biggest problem for me was the ladder to climb up to the (comfortable) loft bed -- with rungs rather than flat steps it was painful barefoot. Shower works well with adequate hot water for one shower. In January, electric plug-in heater was inadequate (due to vented wall and leaky door) even though I like generally like it cold. Wifi works well. Desk and reading light is adequate. I found the couch geometrically uncomfortable for sitting and reading (it converts to a bed). Hosts are very friendly and communicative but are remote. I would not recommend this for more than one person.
Several cafes closeby where you can also work. (Grand Breguet is my favorite).
