My favorite part was how quiet it was considering the proximity to the metro. It is a really perfect spot if you’re wanting to stay in montmartre. The first floor access was super conviennent too. Some things to consider more generally: the hot water only lasts about 7-10mins, the kitchen is isn’t really made for cooking/more reheating, and, in winter, radiators don’t heat a full space (all of which is super normal in paris/europe so not unusual but worth noting in case you’re not used to it). The tub tile did pop out; but it was easy to just push it back in. All in all, Guillaume was really friendly, communicative, and helpful— not in any way that would’ve felt concerning or intrusive. Just a really kind and receptive host.
