We had a great stay at Alvaro's place. It is exactly as described, we found it a very comfortable place for me and my wife, in a very nice neighborhood. Spacious place, good bed, cool lighting, small but fine shower/bathroom. The filled fridge is a great idea and we really made full use of it, having a small breakfast every morning. Alvaro is super friendly and gave us some very good local tips for tapas, drinks, dinner, art, and a good mercado! All in all we had a great 3 days and would certainly stay again if/when we come back to Madrid!
