Calle Hortaleza is wonderful in that it’s armed to the teeth with huge variety of bars suited to many different tastes and times of the evening.
A good place to start the night, and spend a good part of it, is Café Areia.
By day it's somewhere to get lunch or a snack, in the afternoon it becomes a place to chill, and by the evening the vibe has hotted up enough for a cool crowd that passes through on their nightly tour of the city.
Areia is dark and moody; its décor reminiscent of an exotic boudoir, inviting its punters into an environment of intimacy and seduction.
