Gregory’s place has an amazing location! Just north of Republique, you have access to 5 metro lines to go anywhere in Paris. I had some issues with ants (especially after it rained) and the flat was quite dim. Also it seems to be some kind of converted bike or storage space so the heat/AC didn’t radiate well into the tiny bathroom which was always cold. I’m a tiny 5’1” (1,52’) and still had to slide between the door and the couch to get out. Overall Gregory was very communicative via email and seemed very kind. Would recommend for a single traveler where location is your biggest priority.
