where do you think is more convinient hotel for us going to tai tam. inn hotel or panda hotel? .

I’m not sure by Inn Hotel which one do you refer to. But the Panda Hotel is not a good choice actually. It’s too far from Tai Tam. Here I would recommend you several inns nearer.
1. Holiday Inn Express Causeway Bay. It is located in no. 33, Sharp Street, East Causeway Bay.
2. Holiday Inn Express HK SoHo. It is located in no. 83, Jervois Street, Sheung Wan.
