SpringHill Suites, San Jose Airport -- San Jose, CA

Of all the mid-range places I've stayed in the valley, this one works better than most.

In the pro column: the hotel's grass bar is decent, and even has beers on tap.  You can get instant ramen in the lobby, and your room has a microwave.  There's a swimming pool that's not full of rug rats.  It's right by the freeway.  If you don't mind a couple blocks' stumble, there are restaurants and a dive bar a few blocks south by south-east.

In the con column: the in-room coffee makers are old (though there's coffee in the lobby).  The on-site laundry will do a number on your clothes -- like, the "warm" dryer setting is super hot.  And they charge $15 per night for parking.

I say go for it, as long as it doesn't make your commute too bad.  You can split lanes, after all.
