Ibis Hotel in North Point ( 北 角) is quite reasonable. Rooms are on the small side but you can take Airport Bus about 5 minutes walk to the hotel. Very convenient location. Subway is less than 5 minutes walk from hotel. A couple of cheap restaurants around.
The bus stop to get off is just the one before the North Point Ferry Pier, the bus terminal. Takes about 45-50 minutes. Suggest you take the luggage to hotel. The bus has luggage rack. I stayed there once. My sister's favorite restaurant, 凤城, is 10 minutes walk west on 糖水道。 凤城东江菜出名,飲茶也好。 但要记住:对面也有一家凤城, 是冒牌的。 老字号是小的一家。
