The Pool at Heritage Avenida Liberdade, a Lisbon Heritage Collection

"Traditionalists can book at this restored 18th-century town house with paned French doors and a subterranean pool and fitness center"

"Though the dining area/bar is small (and the gym/plunge pool even smaller), the rooms more than compensate with retro fittings and great cityscapes from top-floor rooms"

"The basement fitness center is small and has limited facilities, but it's well maintained and will suit visitors looking to put in a few miles on the treadmill before a dip in the pool"

"But swimmers need only push a button to activate the jets in the heated plunge, transforming it into a handy resistance lap pool"

"Check out the lap pool for a refreshing dip when the temperature soars"
