With great pleasure I write this. Mari Paz received us very well and did give good instructions. The appartment was very nice and very well equipped, ( e.g micro wave, washing maschine) and with sleeping facitities for a Family of 4, if necessary. No air con - but 2 fans. Extremely well located. Walking distance 5-8 min. from Prado, Reina Sofia,Thyssen Bornemiza. Shopping possibilites next door and several good restaurants, including a very good fish restaurant.
An ideal base for a visit to Madrid- and I will come back for sure.
