Hotel Barceló Raval
The rooftop at Hotel Barceló Raval is one of the coziest and warmest—at least in terms of human interactions—in Barcelona. The neighborhood, a rich mixture of cultures and communities, helps visitors instantly feel at home, and the space offers incredible 360-degree views of the whole city. This hotel is a great place to start a visit to Barcelona: The food is good and the cocktails well made—but my personal favorite amenity is its fantastic outdoor pool.
