My high recommendations for Alfonsos apartment as he is great host (speaks English,which is very rare for Spanish hosts) and the room is maximal comfortable specially bed,with great private bathroom.The neighbourhood is local which allows you to feel real Spanish life.
Alofonos place is walkable to all main Madrid points and La Latina metro station is 7min.walk.
Alfonso was always available for any questions and help.Once again my high recommendation as this was really great experience
