I stayed in Madrid for over a week and Alfonso's place was perfect. It's much more than a place to stay, it will feel as if you are really living in Madrid like a true madrileño. Alfonso is a generous host and his apartment is spotless. He makes a small delicious breakfast for you every morning.
The location is perfect for tourists, as you are within a short walking distance of all the tourist spots. It's equally good for those that want something more local because you are a walk or short bus/metro ride away from the more local and trendy neighborhoods as well. Alfonso also provided me with invaluable local advice and suggestions. He knows a lot about art and design and he made my trip spectacular!
