Housed in a huge, 17th century building – slap-bang in the heart of the city – you are just 150 yards from the legendary Santa Ana Square. This square is recognised as one of the liveliest districts in Madrid, home to hundreds of tapas bars, terrace cafes, pubs and restaurants. The Puerta del Sol, one of the busiest streets in the capital, is also a five minute walk, and there’s the Anton Martin Metro Station a mere 200 metres from your room. The spacious dorm rooms are set around a beautiful courtyard, featuring an 18th century Moorish-style fountain, and each one has a shared bathroom. Breakfast is available at the guest house, and there are vending machines dotted around – but the real fun happens in the basement. This is where the legendary parties take place, and it's your turn to join the party.
