Mexico City
Almost every hotel close to Chinatown sits in Mexico City itself, mostly in the historic centre, so the landmark is often a short walk from your room. Hotel Marlowe Centro Histórico is 70 m away, a 1-minute walk, with breakfast, family rooms and free Wifi. Hotel Metropol is 220 m out, 3 minutes on foot, and adds a bar/lounge and fitness centre. Hotel San Francisco Centro Histórico, at 240 m and 4 minutes, is wheelchair accessible and serves breakfast. For a larger property, Hilton Mexico City Reforma is 390 m away, a 6-minute walk, with breakfast, a fitness centre and family rooms.
Cuauhtemoc
Cuauhtemoc holds one entry on this shortlist: Ibis Mexico Alameda, 490 m from Chinatown and about 7 minutes on foot. It allows pets, has a bar/snack/café and parking, and keeps air conditioning and free Wifi throughout — practical for a short city stay built around walking to the landmark and back.
