Consuelo and Alberto were fantastic hosts : very kind and very reactive when you asked them questions.
The appartment was also great, like you can imagine on the pictures, and perfectly clean and functional.
And above all : perfectly located ! We could visit the better places of Madrid just walking from the appartment : Plaza Mayor, calle Cava Baja (fantastic tapas), Plaza Santa Ana, El Prado, Plaza del Sol...
I recommend it !
