This a great, affordable option for a solo traveler. Its tiny, but has everything you will need. I found the street itself to be quiet, just off the main strip with quick access to a few different train stations.
It would be unfair of me to not give you a heads up about the noises you will hear. I’m a NYC resident, so I’m used to thin walls and hearing my neighbors. It wasn’t a dealbreaker for me and I’ll take this over spending a small fortune on a place that is quieter.
A highly recommend using this space to explore Montmartre.
