Wonderful place and great host. Thoughtfully decorated and equipped, and all with authenticity and obvious care. As my flight arrival time was early, Carmelo woke up extra early (for the Madrid standards, at least!) to welcome me and make sure everything was in order. Not just a good host but a great guy.
The apt is perfectly placed. It is a 5-10 min walk to many of the great spots Malasaña has to offer; to my relief (terrible jetlag), while central, the apt is on a part of Calle del Barco that does not get loud, so, even if you choose to go home early, you won't have trouble tucking in early.
