Nice central location in a street that is quiet for the area - Calle de la Cava Baja is a lot busier and noisier.
Small but cosy apartment that fits perfectly for 3 people. Modern bathroom and kitchen with basic standard equipment. Much nicer to go eat outside though in the many restaurants close by. Tempranillo (5 minutes walk) is highly recommendable ! Mercado Della Cebada offering great seafood on Saturday.
Host was waiting for us in the evening with all infos. Not sure why some people put some negative comments. Pictures are very accurate and apartment according to the description.
We will definitely consider this place again next time we travel to Madrid.
