Excellent location, great neighborhood, close to all the main attractions. Yet, the place feels very homey. Claire was a wonderful host. She met me upon arrival in person and also as I was leaving. She gave local sightseeing tips as well. She was very responsive via WhatsApp answering any questions we had. I had to change my arrival plan last minute, but Claire was accommodating. Unlike many hosts in Paris, Claire communicates well in English.
The place was well-maintained and clean and elegantly decorated. There were grocery stores right downstairs, so it was very convenient.
Tips for travelers: The streets around this property including Rue St Charles and Rue Guettenberg offer great medium -budget shopping for clothes, shoes, accessories, etc. Some stores also fill out the VAT refund form for you. We realized this only on our last day, after spending way too much money and time in stores in Champs-Élysées (high end) and Clichy (low end).
