Sarah is a nice host, we landed in late hours but still managed to check-in anyway. Once in Paris, she provided her contact to help us if we needed. The place is close to the metropolitan wich is a good transport to visit Paris's interest points. The house is small but has pretty much everything the guests could need and it's well decorated. The negatives are that it isn't as clean as it could be, mainly under the bed and in corners (as an allergic to dust I suffered a little bit) and when we checked out we found a homeless person sleeping inside the building, but that doesn't really depend on the host.
Overall it covers the needs and it's a good option for travellers in Paris
