Staying at David's place is nothing short of awesome. He is a wonderful host who even cooked a local dish for me and another pair of visitors. For me, he even upgraded me to a better room free of charge! His locations really really good. It's very near to the shopping belt of Madrid. When I am tired from walking, I just walk back to his place and nap, and then continue later. If I were to visit Madrid again, I'll very likely to stay at David's place again.
