Javier's place is nice and cozy for a 3-4days stay in Madrid. He is quick in response and welcomed us below the building. There are two nearby metro station, which are walkable within 5mins. The Atocha train station (AVE..) are nearby too, if you are coming from other cities from Spain. There are bars and restaurants right below the home, so you do not worry about not getting any food if you are hungry.
