When yet another China Southern flight was badly delayed, we missed our connection to Shangri La, and we had to either decide to sleep at the airport or at Best.
We made the right choice.
Pros : The hotel is a few hundred meters from the airport and is easily reachable by the overpass connecting the departure hall and the hotel, just follow the signs. Rate was really good, something around 70€ I think. Room was VERY clean and it could match a 4* hotel by European standards.
Cons : At the reception they have like 6 computers but it still took 20 minutes to check out. Remember to keep you deposit receipt because they will need to match your copy with theirs, it all looked very bureaucratic. We tried to have dinner there around 8:30 pm, and all dining options were either closed or being closed. We ended up at KFC at the airport.
I would recommend it for a short stay by the airport.
