I had a great stay in the studio. The location is amazing, the area feels calm and safe. It's also close to shops, restaurant and beautiful sites.
The studio is small, but it has almost everything you need and it is nice and clean.
However, I have to mention that the current bed is quite uncomfortable, which is a bit of a downside, if you're there for a longer stay (there is an extra mattress topper, but it didn't make that big of a difference).
Marie-Hortense is a very welcoming and responsive host. I had some trouble late one evening, where my key bipper didn't work. She luckily responded very quickly and helped me out.
