Although my overall stay in Manon's studio was positive, there are a number of things someone should know before booking this place.
1. It's at the 6th floor and there is no elevator
2. The toilet is outside the studio and there was no light during the night
3. The shower was very small, so if you are tall you might find it challenging to fit and have a shower.
Other than that, the studio is located in a wonderful neighbourhood in Monmarte, near everything someone can be in need for (public transportation, supermarkets, restaurants eth) and Manon was immediately responding and really helpful.
