Helene's and Marc's place was absolutely wonderful. The location was superb: across the street from a taxi stand, around the corner from a pedestrian street filled with many restaurants, a block from a major metro stop, above a boulangerie, across the street were 2 ATM machines, 5 minute walk to the old town and pedestrian pathway along the
Rhone where you can rent velo bikes, 20 min walk to Les Halles de Lyon, 2 min. walk to the Tourist Info Center at Place Bellecour, across the street from the start of the main pedestrian shopping area.
Helene was waiting for us in front of the apt bldg when we arrived by taxi. She gave us a map of Lyon and there were other travel books available.
Communication was easy from start to finish. The apartment was spacious, bright, well supplied, modern, spotless, and comfortable. Helene gave us the number of Taxi Lyonnaise so that we could reserve a pickup at 5:30am to the Gare Part Dieu. The taxi was waiting for us across the street at the taxi stand. Fare was about 15 euros in Sept 2018 and ride was 10 minutes with no traffic. I can't imagine a better place to stay.
