Best host ever! (and I travel a lot...) Very warm and personal welcoming, good local recommendations, communication really fast (y además en Español! :) . He was very kind and flexible with our late checkout.
Second floor, old building without elevator, but new apartment. Bed extra large and comfortable. Good isolation (couldn't hear the neighbors' Xmas parties from de apartment). I appreciated the basics (oil, salt&pepper, shampoo.. )
Public transportation (metro/bus) 3min walking far, old town 10-15 min walking.
