We had a great time staying at Ian and Alberto's place. The apartment is very roomy and definitely suits two couples. It was easy to find the first time there and having an elevator made coming home after late nights so much more enjoyable. La Latina is the perfect neighborhood to stay in as its accessible to many of the Metro lines and an easy walk to the Cercanias at Puerta del Sol. Great tavernas in the area, especially the one at the corner of Calle de Calatrava and Toledo. We would definitely stay here again when we're in Madrid.
