Lovely apartment a block away from Atocha train station and the Reina Sofia museum. Two metro stations are nearby and can take you everywhere in the city while the neighborhood itself is quiet and has plenty of places to grab a coffee or a bite. All of the amenities you would need are present, including a full kitchen, washer, etc
Our only issue was the lack of ac - the apartment got quite hot in the early summer, but for other times of the year I would not hesitate to book again.
