Overall I had a great experience! The location is lovely, perfectly situated in the heart of Paris. Close to bars, restaurants, Velib (public bike rental), and many area attractions. The owner is highly responsive and very fast to respond to any questions!
Just one note for non French speakers, there are a couple notes in French only that you should be aware of. It says they'll ask you for a $200 Euro deposit on arrival, you may not have that much cash on hand. Also, it says you can only check out between 8 and 2200 (10pm) or there will be a $30 euro penalty (though on arrival I was told it was 9 - 2200 and a $50 euro fee?). I wasn't aware of this before hand so I was slightly surprised by the info.
All the best!
