Michael's flat is pretty much brand new, and in a great location but there are several massive drawbacks to be aware of:
1) It's on the ground floor of a very noisy street. There are bars all around it and you wil hear the noise of people drinking on the street and also stumbling out at closing time. (And using the outside walls as a urinal)
2) It gets VERY hot, and there are no fans provided. The only ventilation is from a small window over the door and from the windows in the bedroom, which open inward and have no curtains so no hope of privacy if you open them.
3) No curtains means the streetlights shine through the windows in the main living area. If you are sleeping on the sofa bed, it's almost day-light bright out there.
4) The WC is moldy. If you're sensitive to mold or musty smells this will be an issue for you.
We loved Lyon, and loved the location overall. Michael was flexible with our checkin and prompt with communications, but buyer beware of the issues above.
