We had a wonderful time at Lionel's apartment!
It's in a very central location, in a fun neighborhood with many cafes and shops, and conveniently right by the Saint Paul metro station.
The apartment is large and spacious and offers a great rooftop view of the area :)
We were four guests (2 couples) and there was plenty of room for all of us.
Although he was abroad when we were visiting and we didn't get to meet him in person, Lionel was very communicative and organized and made sure we had everything we needed.
I highly recommend this flat to anyone looking to stay in the center of Paris!
