Consuelo is a very loving and nice host.
The room is comfortably furnished and you have everything you need. The mattress is also comfortable and the whole apartment is also very clean.
The bus is very fast from the airport directly to the accommodation and with the metro in the center of madrid you are also fast.
Consuelo also gives great tips for the city.
I can only recommend the accommodation and I would come back anytime. :)
