Alphonse's apartment was large, clean and in a fabulous location. There was a patisserie on the block and a grocery store very close. The location is perfect for seeing Lyon, also. Some sites are within walking distance and the train station is a 5-7 min walk in a neighborhood that felt very safe. We had a car with us and found parking to be challenging and expensive. Overnight on the street was free but it was hard to find a spot. The train station parking lot was quite expensive.
The apartment looked like the pictures and was plenty big for six of us(three couples). There were six beds and pull out sofas so it can theoretically sleep a lot of people but I'm not sure how comfortable it would be for more than 8-10 people. The elevator works fine but the stairs are nice and wide and it's not a bad climb to the 3rd floor. At night the neighborhood was quiet. The building is secure and safe.
We did have a few communication issues getting an enough towels for each us and asking questions to the person that was assigned to communicate with us but, nevertheless, checking in was fine and the information was good. There wasn't any information about Lyon around the apartment but we knew someone locally so it wasn't a big deal for us.
All the rooms were very clean and beds were comfortable. The one room with the chimney had two beds in it(as did the others) but it is difficult to climb around the chimney to the second bed. The other two rooms are a little bigger and accommodated the second bed much better.
The kitchen was well stocked with dishes and glassware. Thankfully, there is a washing machine/dryer which we needed for our extended vacation. We liked the high ceilings and traditional style of the flat. I would definitely recommend this flat to Lyon visitors!
