The flat was very nice, even if a bit on the small side for three persons. As we didn't spend that much time in, it wasn't a problem. Good for a couple or close friends. Everything worked. The location is perfect, very centric, yet the street was surprisingly quiet and tranquil. Jesus was a good host, however as I have lived in Madrid before, we didn't really need any tips or anything, so don't know about that :) Muchísimas gracias Jesus y hasta la próxima!
