Only 3 min. walk from gare de Lyon. Very easy to get there. Little calm pedestrian street with small colorful houses. Brand new apartment, I was the first guest. So everything was very clean and nice. Small but cosy place, bright, has everything you need, furnished in a nice, relaxed style. Comfortable bed. Very nice bath with clean design and quite spacious, compared to the size of the apartment. Joffrey anf staff were very responsive, kind and helpful. Easy to get everywhere by walking from there.
The staircase is very narrow and steep, just to keep in mind in case you are traveling with a big/heavy suitcase or have reduced mobility: not your place, there is no elevator.
The whole house has airbnb-rental apartments. One on each floor. You can easily hear the other guests, especially coming and leaving. But they were on the quiet side when I was there, so it was not an issue.
Otherwise i can absolutely recommend this place.
