Concierge.com's insider take:
Numero Uno, one of a handful of beachfront guesthouses in San Juan, feels like a stylish friend's beach house. The three-story 1940s structure has only 14 guest rooms, and the management throws weekly cocktail parties on the second-floor lounge's balcony. The decor eschews tropical kitsch in favor of sophisticated shades of ocher and taupe. The plunge pool, with luminous black tiles, sits inside a walled garden with bougainvillea and other tropical flowers. Tables at the Caribbean-style Pamela's restaurant spill out through the hotel's archway and onto the sand. Best of all is the location: The mostly residential Ocean Park sits between Condado and Isla Verde. That means you get to be right near the action without the attendant traffic, noise, or high price tags.
