I really enjoyed staying at Andres's place. The apartment was very close to the Palace and all the main sites in Madrid. To walk from the Palace to the Plaza Mayor and great shopping is about 15mins and to walk to the Prado Museum at the other end of the old part of Madrid is about 40mins or a 7Euro Uber ride.
The apartment is modern, clean and has a small kitchenette with everything you need including a washing machine. Andres kindly left some tea, pod coffee, a chocolate bar and some cake to get my stay off to a good start. For more food supplies you simply need to walk to the corner, cross the road and you'll find a very convenient supermarket.
Andrea's thank you for your prompt communication and arranging my transfer from the airport to your apartment.
