I enjoyed my stay at Paulines studio and it was much as represented. I was never aware of Paulines presence. If she were on occasion in her studio, I could not in anyway be certain. The street is quiet and the apartment has all amenities.
I do think it depends on what one wishes to see in Paris and how one chooses to see it. I'm not much for dressing for dinner or going out for the day to walk some blocks to and from either the bus or metro, especially in bad weather or at night. This should be considered when choosing this location. If you don't mind, this is a wonderful apartment to consider.
I used Uber back and forth , twice a day to take myself to the museums and Paris center. The charges for this service certainly added to my accommodation expenses .
Its a small space so consider your luggage requirements as well. Light travelers will manage the storage of these items.
Pauline is very responsive to any question or inquiry. She is a gracious hostess and depending on what type of traveler you are, this apartment would be a great choice.
