Concierge.com's insider take:

This longtime Provincetown fixture was starting to look worn when new owners—who also bought the Crowne Pointe Inn across the street—took over in 2008 and shined it up like new. Comprised of nine buildings surrounding a private courtyard with a pool, the Brass Key has a pleasantly compoundlike feel that makes it an unlikely oasis in P-town's densely populated downtown. Its almost entirely gay clientele includes many regulars who have returned for years, elevating the guests' average age. So, in the hope of luring a younger crowd—not too young, though; no children are allowed—the owners have brought in new furnishings and replaced the bathrooms in nearly half of the 43 units (so far). Also in the works are two new suites. The rooms are masculine and tastefully decorated with reproduction furniture, but guests spend less time in the rooms than around the pool and in the many public spaces, including a high deck in a turret that's popular at sunset, and a living room–like lobby with comfortable couches and a piano.
