I enjoyed my stay at the Holiday Inn Express, Shangdi.
It is located about 10 minutes from the subway station, of the same name. In addition, there are various restaurants, a supermarket and a 7 Eleven close by. There is also a Walmart Supercenter two stations away at Zhichunlu (exit B).
The room was clean and comfortable, and the wifi worked great. Once you sign in, you receive a 7 day account. I did not watch t.v., but the bathroom was nice and there was plenty of hot water each day. The hotel provides 2 bottles of water, coffee and tea for free in the rooms.
Breakfast is served each morning in a room just off the lobby. They serve a variety of food, both Asian and Western (eggs, toast, cereal, bacon, sausage). The buffet has different items daily. For example, on Monday, I had bacon, chicken sausage and dumplings with my breakfast. On Tuesday, they had beef sausage, chicken nuggets and what looked like small spring rolls, but were filled with bean paste (not very good), no dumplings, bacon or chicken sausage.
The front desk staff was pleasant, efficient and spoke a good amount of English. I arrived a few minutes before 12 and they allowed me to check in.
I would recommend this hotel and I would stay there again, also the hotel was quiet and there is a sign on the font desk warning of the fine imposed for smoking in the rooms.
