The studio is extraordinarily well located: literally 5 minutes walking to Notre Dame. It is also very well communicated by public transport to the rest of the city (the Louvre is less than 10 minutes away by metro). The neighborhood feels safe and has lovely boulangeries and little shops.
The studio in itself is small but well organized and has everything you might need. It is perfect for one person. I was surprised by how quiet the studio and the building are. The only slightly uncomfortable aspect is having to climb through a ladder to get to the bed, but, again, the location more than makes up for it!
