As a female going solo to Paris, my main concern (after the search for a super cute loft) was safety. Not that safety was anywhere close to an issue with this stunning area. This spot has got a secured entrance, lighting, a quiet court and lovely people in building. Perfect location. In addition, Louis was a superb host with fantastic communication. The apartment was tidy, quiet and felt like home. Coolest part was the loft bed. I would definitely stay there again. Merci Louis!
