Small apartment in old building but fully renovated.
The accommodation is spare/not luxurious but perfectly clean. Good kitchen, fully equiped.
Living area - couch, table and TV - is sparsely furnished but completely functional.
The apartment location is more or less perfect for visiting all the famous museums - Prado, Reina Sofia, Thyssen etc etc.
And has a fantastic selection of restaurants, bars, cafes etc in the neighbourhood around it.
It is good value - I would go back to this apartment again.
