I like:
1. the location: great place for tourist and party animals, closed to almost everything you want to do in Paris
2. Quiet: the studio faces the interior yard which is very quiet day and night
3. very clean room: floor, bed, washroom
4. Mezzanine: fit for max 4 ppl with at least 1 couple or a family of 4 max
I don't like:
1. No elevator: I know, that is Paris. but more and more building intra-muros has
2. it is a studio, so everything, except the washroom, happens in the same place, no clear separation of functions, compared to 2 pieces or more.
Conclusion: I am satisfied with the stay
