I stayed for a few days and everything was great!
Check-in and check-out was with Colette. She was very helpful and communication worked well, despite my poor French language skills. The location is great, and you can easily get around by walking, taking a bus, or riding a bike (there is a bicycle sharing station (Villo) nearby, which is very inexpensive). The apartment is unique and stylishly decorated. There is good WiFi / internet connection, which was important to me for work during the day. The kitchen is well-equipped, and I liked that the trash is separated with different bags for recycling. The bedroom is very nice and has a big and comfortable bed. The bathroom includes a nice and surprisingly big shower.
Overall, I can definitely recommed this host and the apartment, and I would book it again. :-)
