This is not the kind of place you'd expect to find in Lavapiés which is known for being an ethnic melting pot with a bohemian atmosphere and an eclectic mix of cuisines.
This rooftop terrace sits on top of the ruins of Escuelas Pías - a convent dating back to 1721 - which was burnt down by an angry anti-Catholic mob during the Civil War. You wouldn't realise this gem is there unless somebody tipped you off. If the library is open you should sneak in to take a peak, otherwise ignore the lift and go up the stairs to get the full experience.
It’s open all year and there's a cosy indoor area in case it happens to be a windy day. The décor is very organic, at night the luminous furnishings create a warm and welcoming atmosphere. The food is simple, Mediterranean style dishes that are perfect for sharing.
The vibe is super laid back and you'll find all kinds of people ignoring each other - bohemians, intellectuals, posh, etc.
There is something very special about getting drunk at heritage listed venues - the hours will just fly by. The only downside I could find is that it shuts early.
