Close to the airport
Hotels in the airport area tend to be expensive - or just unrecomendable I found Hotel Riazor (flash-only site - I found some unofficial fares, another site referring to it), which seems to offer a good balance - It is a nice and clean hotel, offers free transportation to the airport, and has decent fares: Apparently, starting at MX$715 for a double room, MX$1090 for a Junior suite for four people. Be sure to check with them -
