The hotel is not called Courtyard by Marriott anymore. Now it's called Pentahotel. The hotel is in a good location and breakfast is okay. Superior room with a king size bed is a very good option. People working in the hotel speaks a very limited English, so it's difficult to comunicate with them (it happens the same all over China...) They lie about internet, because they say that it's free and it is not free. They charge you about 60 Y per day. If you complain about it, they say that it's not Marriott.....
