I was in Shenzhen for work, and the event location was about 2 MRT stations away from Asta Hotel. The MRT entrance is just outside hotel main door, so, it's rather convenient. However, there're constructions going on at this time, as there's no lift to the MRT station and the staircase to the station is very very long, for those who're carrying a big luggage or bulky bags, it can be quite tiring to walk the long long stairs. Not sure is it because of the constructions, we can't seemed to find breakfast within 5mins walking distance. Toilets are clean.
