A couple options, probably more coming from the Vets who live there....
http://www.sleepinnsanjose.com/ In the heart of downtown, less than 1 block from the Del Rey, a very nice business hotel, Not very chica friendly, maybe a fee, not sure, but they frown upon it
http://centralamerica.com/cr/hotel/cariari.htm On the Autpista on the way into town, Not sure about chicas,but is a very nice hotel, stayed there 10 years ago on a business trip... (maybe a 15 minute taxi to downtown, more during rush hour)
http://www.sanjosehotels.intercontinental.com/ Very close to Cariari Very nice, very expensive.. NO Chicas (maybe a 15 minute tax ride to downtown, more during rush hour)
Hope this helps
