This apartment is perfect! Small but elegant, with charming touches and an amazing location. The bar right next door, El Alembique, is friendly and does good food, and the whole area is lovely to walk around for tapas. Easy to get to both Reina and Prado - not 5 mins walk - and indeed to walk all around Madrid's old town. Paula and her partner could not have been more helpful, with thoughtful touches like leaving coffee, fresh bread and fruit preserve in the fridge, and allowing us to store our luggage on the last day in their gorgeous coffee/chocolate shop at #20. They also printed out our train tickets - a lifesaver. We'd highly recommend this place and hope to return.
