    My father and I stayed at the South Lake Hotel for a week when we visit Beijing last month. It is in the downtown area, but it is easy to go to anywhere from the hotel by public transport.

    We lived in a comfortably double-room with a big bath. What I liked best were the free high-speed Internet connection in the room. I checked my email messages every day. I also shared for my friends many photos taking in Beijing. The food was wonderful with reasonable prices, and we enjoyed several local dish.

    It is such great hotel that I would recommend it to any friend of me who is going to Beijing.
