The apartment itself was magnificent. A perfect neighborhood in old Lyon, and a beautiful, huge space. We were close to everything and truly enjoyed our stay there.
However, our check in experience was less than ideal. The listing implies that check-in is 24/7 and a concierge is always available, and check in time is 3pm, so since I didn't hear from anyone before the day of check-in I of course assumed everything would be ready by 3pm and that it would be obvious how to get in.
We arrived at 3p to a locked building gate with no indication of how to get in. I tried several times to call the host, but nobody answered the phone. At 3:30 I finally received a text that said that the previous occupants had still not vacated the apartment (!!!) and that it wouldn't be ready for check-in for a while. I asked if we could at least leave our luggage so we could go grab a bite while waiting and she said she would arrive in another 20m. We didn't necessarily mind exploring while we waited for the apartment to be ready, but having to wait almost an hour to even drop our bags off was unacceptable.
I'm still giving 4 stars because the space itself was so exceptional, but the check-in process needs serious improvement.
