Daniel's Airbnb is a room with a WC and a curtained-off sink and shower that is located just off the entry vestibule to his own apartment. It has a private, lockable door (as does his apartment), so you have privacy. There is no elevator in this very old building, as I think Daniel mentions, so be prepared if you're hauling luggage, especially since you already will have climbed uphill to get to his building. But the best reason to travel light if you stay here is this a really small room, with no storage at all for your unpacked clothing or your suitcases. My wife and I are experienced travelers who travel quite light and are accustomed to small rooms, but this was a very tight fit for us, and we frankly think the room is better suited for solo travelers.
That being said, the room was clean and comfortable apart from the close quarters, and it is in an interesting historical area of Lyon with access to some lovely neighborhoods, such as La Croix Rousse and to metro stations that will take you to Vieux-Lyon. Just understand that Daniel's is a residential neighborhood partly up one of the prominent hills of Lyon, and to get up or down to restaurants and other businesses, or to catch the Metro, you will be doing a lot of walking up and down steep hills and stairways built into the hills.
