­"Get thee to a nunnery" may not be such a bad thing after all, considering the recent slew of monasteries converted to luxury hotels. There's the Four Seasons in Prague, as well as The Augustine there, and the Certosa di Maggianoin Tuscany. One of the most interesting hotels with a divine pedigree is the Parador de Santo Estevo in Galicia, Spain, a former 10th century monastery. There are 77 rooms dotted around three cloisters, and one of the hotel's top selling points (apart from its secluded location) is its new $2 million spa. The 9,6000 square foot space features a flotation tank, Vichy showers, and an extensive spa menu (Celtic massage, anyone?)­
