Cinthia is very helpful she is willing to share information whatever you need to travel around in Madrid (especially Transportation information). From airport to the house is a bit far but you can reach to city centre like Sol square approx 30 mins by metro (10 mins walk to the station). It is quiet neighbourhood and safe too. There is no AC in the room but Fan has. I felt warm while I was sleeping but this year summer in spain became exceptionally extremely hot. Gracias Cinthia :)
