Lisa's place is an adorable room.
The rooftop view is amazing. If you are a fit-person and does not mind to take the stairs for 7 floor then Lisa's place is a great deal. 5/10 minutes from Notre-Dame de Paris and other important monuments, the small apartment is located in a very interesting area.
There are plenty of bars and restaurants and a yummy "burger restaurant" just down on the road (Schwartz's).
Lisa was very flexible with the leaving time, we much appreciated that.
High suggested place, I would come back in case I will go to Paris again.
