Beautiful room including private bathroom and access to a well equipped kitchen located very close to many of the awesome sights Madrid has to offer (Parque del Buen Retiro, Museo del Prado, Plaza Mayor, Puerta des Sol, ...) - and all of this for a totally fair price!
Maria was an extremly kind and courteous host.
My travel partner and I have been completly satisfied and would visit Maria any time again when we are back in town.
