We had an enjoyable stay in this studio in Lyon. It is perfectly situated in a lively area in the middle of Lyon and yet you don't hear any street noise in the studio. The set-up of the studio is functional and comfortable. The mattress and pillows were of good quality and very comfortable. We arrived in Lyon a couple of hours before the check-in time and Willy from Hosting Services was kind enough to let us access the studio early.
However, there are some small touches that could be improved on to make the overall experience more comfortable and homely. For example, enough coffee pods for 1 per person per day of your stay, washing detergent for the washing machine and body wash/soap in the shower (we were only provided with 2 small hotel style bottles of shampoo).
Overall, it was still a positive experience but just some slight improvements could make it better.
