We stayed here for 4 days in June. The weather was very warm but the apartment remained cool and comfortable. Helps to have some knowledge of French when communicating with Alexandres father who was very helpful and knowledgeable of local amenities. The curtained off bedroom works very well and there is a small wardrobe with hangers for clothes.
We did not use the cooking facilities while there but there appeared to be plenty of equipment should you wish to. There are plenty of places to eat in St Just or further into Vieux Lyon. There is a handy fruit and grocery shop next door and a boulangerie two minutes walk away,
Public transport is easily reached - a ten minute walk to St Just to access the funicular which connects to the metro system.
All in all a very good location which is away from the noise and bustle of the city yet provides easy access to the public transport system.
