If you have found this apartment, book it! It is in a fantastic location for all of the attractions. We only used the metro to get to and from the airport and for a day trip to Segovia. Everywhere else is within walking distance. The apartment is lovely and quiet with everything you need for a short stay. Juan Carlos is lovely; extremely helpful and easily contactable. As well as his recommendations in the guidebook we recommend La Buga del Lobo, Calle de Argumo. Thank you Juan Carlos!
