This is definitely a good place if you are quite budget on hotel. The room is good enough for 2 person and it has everything you need. It is located just one road down the Mongkok MTR Exit E2, so you will not have any trouble finding the place. Just that the entrance is quite small so I went slightly a few shops ahead. However, Danny was very helpful, he will provide all the directions:) If you have any questions or problem, you can ask him too.
The check-in time is about 1pm, so actually it's not good to have a midnight flight as the shops also only opens at 11am.
Overall, the experience was great:)
