This is a fantastic hotel that is close to the metro, the Latin Quarter, and (of course) Notre Dame. It's very small and often books up early, so make sure to book out at least 2 months in advance, especially during the high tourist season.
Speaking of small, do not stay here if you are claustrophobic. The hallways, elevator, and the rooms are small. Like, Tokyo small. Luckily, you won't be in the room much, because hello, you're in Paris for fuck's sake.
The staff is very friendly and are available on a 24 hour basis for your every need. With the location added, this is a must stay if you're floating through Paris and want a truly intimate visit.
