Mathilde's apartment was the perfect spot for all of our explorations in Paris. We were able to walk nearly everywhere we wanted to go from her central location and the closest metro stop had lines that went nearly everywhere else. There were spots close by to get food for self-catering and anything else you would need. Despite the central location the apartment is located on a very quite side street. We were able to sleep with a window open to let in the cool night air without disturbances. While we didn't actually meet Mathilde during our stay -- she checked in on us several times to make sure we were doing alright and the arrangements for arrival and departure were very easy!
