The airport BW is probably the most convenient but featureless and pricey (busiest tourist season in PR). If you wish only to crash try the Borinquen Beach Inn for 30-50% of the BW price (add taxi fees or take the cheap city bus). Its a 1 star, noisy, featureless, has free internet and is cheap. There are some Canario motels about 2 star that are ok. Nil cheap hotels in Isla Verde area.
