Sebastien’s place is perfect if you are just needing a small, local place for however long. I stayed alone for a few nights and it was perfect for me. It is close by to grocery stores and the metro, and everything that could be needed was provided. Sebastien gave me some very helpful information about the area and places to dine/shop at. Any slight ‘issues’ about the place are mentioned beforehand e.g. the flight of stairs (which aren’t actually too bad) and the low ceilings of the mezzanine. He also responded quickly whenever I had a problem. I would definitely stay again if I ever come back to Paris.
