Mathieu responded quickly to our enquiries and facilitated an easy check-in and check-out. We only stayed for one night, as we were three adults and the space is very small with one double bed, a sofa bed in the living area, and a bunk bed which is too close to the roof and without a fence as protection in case of any falls.
We didn't like the bathroom because it didn't have a door (lack of privacy) and the shower was very unconfortable, too small.
I requested a refund for the next two nights and Mathieu kindly accepted to proceed with this process, understanding that the flat wasn't suitable for us.
