Hotel Diagonal Barcelona is a slick hotel on Avinguda Diagonal that occasionally hosts parties on the roof, especially during Sonar Festival. The rooftop is a wood-paneled space with a small pool and room for less than 200 people. Mobilee, Resident Advisor and local promoter Monkey Bar have all put on daytime soirees there, usually running from 2:00 PM until 9:00 PM. Due to the small capacity of the space, most events are invite-only.
