Maria's place was really nice, bright and clean. We kept in touch and easily found each other to get a key. We stayed in Lyon only for one day so we didn't use the apartment that much, but everything we needed was there.
The only thing that bothered us was the toilet. There is a separate bathroom (with no toilet) and a separate toilet with the toilet seat - and that room that was literally way too small for a person to fit in. The seat was a few centimeters away from the door and we were barely closing it (some of us couldn't close it at all) - men and women. We saw no images of the toilet and the info about this issue. It would be nice if, at least, we had idea about it.
Other than that, the location is pretty great - it was quiet, but lively and very close to the things we wanted to see in beautiful Lyon.
