My family and I stayed at Sebastien’s flat and it was wonderful!
The location was amazing! Right near the Parc Tête d’Or (less than 5 min walk) which if you are traveling with kids, is a MUST! It was also really close to yummy food and a grocery store as well as public transit. The apartment had lots of kitchen amenities for making meals at home and it was very nice to have a washer available for use.
It did get pretty warm in the apartment during the day (we were visiting during a heat wave) so you should be aware of that BUT it was a super location and communication was very easy and seamless.
