The Marriott City Wall is very well located, close to downtown. Excellent rooms, absolutely clean and spacious, really comfortable bed, two TVs, and can easily accommodate 2-4 people. The lounge serves a good breakfast, so if possible, try to skip breakfast in the restaurant (too crowded). The bar serves a nice salad, as well as sandwiches and other appetizers. There's a happy hour at 8 pm, when you can enjoy the second drink for free. Good choice in Beijing.
