Michel’s place is very small and the photos were quite deceiving, the top section where the bed is is quite an uncomfortable area to sleep with the roof very low and impossible to sit up without hitting your head. It is quite a claustrophobic space. There appeared to be some mold on carpet of the steps and the windows were quite unclean. In terms of location, it is very close to the Champs-Élysées, and has a number of bars and cafes within 100m. It is close to the Metro 1 so arriving via public transport is easy.
I would recommend Michel’s place for one person who is interested in being out for most of the day, but the bed is not easy to sleep for two people. Be prepared for a small flat if you book this place but very good location.
