The Glasshouse, Edinburgh $$$$
Concierge.com's insider take:
With glass walls dramatically studding the facade of the 150-year-old Lady Glenorchy's Church, this high-design place next to the Edinburgh Playhouse is self-consciously hip. The 65 spacious rooms have, ahem, b&w art photos of naked women on the taupe walls, polished wood floors, slatted room dividers (in the suites), terraces (mostly), and heated-floor glass-walled bathrooms—and indeed glass-walled walls: The windows are massive. It's all part of a posh mall with a multiplex movie house and pubs. Arguably, the nicest feature is the hotel's roof garden. Replete with lawns, an arch-shaped covered deck, and all-weather armchairs, it's the only one in the city (which says more about Edinburgh's climate than its architects).
