Nicolas was very friendly, super responsive and made sure our month-long stay went smoothly. The main area has a bright, practical kitchen opening onto a good-size living room, plenty of light and exotic plants which made it a lovely space to be in. The windows open onto a plant and tree-filled courtyard and small street, which was very nice. The neighbours were also very friendly.
A few cons: we didn't expect a ladder to get from the entrance to the main area upstairs; the bathroom is in the downstairs room (opens onto it, no door); most doors don't close properly; the bedrooms are very tight (especially downstairs). The downstairs mattress was very hard and needs replacing—but I think this is an easy fix.
Overall I would say this is a great place for shorter-term stays.
