We had a great time staying in Alfonso's lovely little apartment. It is beautifully decorated and the place was sparkling clean when we arrived. The location is indeed very central, with most Madrid destinations walkable and some (Reina Sofia) VERY close! However, given how nice the apartment pictures look, we were imagining somewhat more of a picturesque neighborhood -- which is not the case. Pretty grungy around, but safe. I was fine with that, but my parents were a bit disappointed with it. Overall, I gave the apartment four stars instead of five because it was a fabulous value and really a very nice place, but clear that nobody actually lives here full time because small things were missing. Washing machine but no detergent, half-length shower curtain that meant the bathroom tended to get soaked when anyone showered, general small size of apartment (this place would be PERFECT for two people. was definitely a bit cramped for four people.). All that being said, Alfonso was an extremely kind and responsive host, and I would recommend this apartment.
