Unfolding behind a Modernista façade dotted with metallic orbs, this beautifully designed hotel gets almost everything right, from the top-notch service to Romain Fornell's Michelin-starred restaurant Caelis to the lovely rooftop terrace with bar, glassed-in pool and twinkling views of Montjuïc. The sleek modern rooms have lavish fabrics, pendular lights, iPod docks and, for most, in-room shower cubes (lacking privacy).
There's also an enticing wine bar, as well as a 24-hour gym and sauna.
