Although we arrived to a place that hadn't been cleaned properly due to the fact that their plane back in town was late, giving us no choice but to sleep elsewhere, Valérie and Jean-Christophe did everything they could to correct the situation: they fully refunded our first night and did a very proper cleaning as soon as they arrived. After this initial pickle, everything went very well.
The apartment has a very warm feeling, it does feel like it's a home. It is located in quite a nice part of Lyon, close to many great restaurants, shows and various other activities.
A safe bet.
