The host made us feel really welcome: she was very helpful and answered our questions very quicly before our arrival; then she came and met us at the metro station.
The studio is quite small but there is everything you need and it is in a prime location near a lot of bistrot and restaurants, and important sites like Louvre, Centre Pompidou, Saint Eustache Church, Notre Dame, Canal Saint Martin and Opera. It's a 20 or 30- minute walk from the flat to these places of interest, but if you don't like walking, the metro station is very near. To sum up, we loved our one-week stay in Paris!
