Excellent place for a few days and probably best for a solo traveller, clean, pretty small, really good location, not far away from Montmartre, a lot of cool cafes nad pubs in the area. Host was very helpful and communicative. The only downsides were the thing that the place was very cold when I arrived and it needed at least few hours to get warm. And one time when I was in the middle of the shower while hot water ran out and it is winter outside, so not the best experience. Also noisy neighbours, but if you are most of the day outside it doesn't matter.
Overall I recommend this place!
Merci!
