Alvaro was the perfect host. His flat had everything we needed - he was more than happy to offer his recommendations of what Madrid has to offer, as well as local picks for ideas for restaurants close to his house. His flat is also ideally located to explore the main sights of Madrid - it is literally across the road from the metro, and also its in a position which makes it easy to walk to the main sights. I wouldn't hesitate in recommending a stay in his flat.
