The room is on the 3rd floor, it doesn’t have air-conditioning, but there is a big fan on the ceiling. The room is well-equipped, bigger than I thought it would be, bc the sofa bed was a bed already without having to pull it out.
I think it is better suited for a solo traveller, the check-in and communication with the hosts was easy and fast. Also, location was great near numerous metro lines and buses. There is a big monoprix just 3 min away, and a biocoop also 3 min away to the other direction. Saint-Denis is a really popular plce near Les Halles, so it can be a bit noisy at night.
