Catherine’s flat has a ton of pluses. I stayed 2 separate times in December. She’s an extremely accommodating host. She worked around my travel schedule for check in/ out and was able to leave keys in a lockbox so I could easily access the flat. She checked in regularly to ensure all was well. The location of the flat is super. It’s on a quiet side street close to great restaurants and easily accessible by metro and the RER B line (walkable with luggage). The apartment is quirky & unique & really makes you feel like you are authentically living in Paris. There are numerous seating areas in the flat & the desk made for a good work space. The washing machine is a huge plus. The flat is on the 4th floor. So, plan accordingly with luggage. The stairs are wide & easy to maneuver but it’s still a lot with baggage. I also would have liked the apartment to be a bit cleaner upon arrival. It didn’t feel professionally cleaned. This wasn’t enough to negatively impact my stay. Overall great!
