Great apartment in a great location in old Lyon. The entry and front is pretty classic old Lyon so expect it and be ok with it as part of the experience. The entry/check-in is pretty smooth once you figure out which is the right "hallway" to enter and how to work the locks.
The location is great and about as good as you could ask for unless you want to be up the hill. You come right out the front door on the main part of the old town and just start walking and exploring/experiencing from there, including the museums and historic sites in the old town. There are a number of classic Lyon cuisine specialty restaurants within easy walking distance as well as the normal range of other options.
The apartment is newly redone and well stocked. If you have 4 staying, there is some managing privacy around the bedroom/shower/toilette layout and usage, but nothing too complicated. If you want to experience Lyon, this is a great place to do it and there is paid parking on the river a couple of blocks away.
