A bargain-priced design hotel for grown-ups, the Ciutat Barcelona has a soothing contemporary look to its rooms, including chairs and light fixtures that could have come straight from the showroom at Design Within Reach. Spaces are compact but well-designed, and the rooftop terrace is like having a private oasis in the middle of the city. There is a side entrance for wheelchair users, and some of the rooms are accessible. The small pool is big enough to make kids happy.
