We had a great time staying in lyon, and the flat was good, it is up 5 flights of stairs which can be tiring after a long days exploring. Everything was perfect until or second to last night when the fire alarm battery started running out and would beep every 2 minutes. This happened for 2 days as a ladder was needed apparently, we were told to use the ear plugs under the sink however I dont think this was the correct way to deal with it. Otherwise, nice stay
