Federico and Betina, his sister who helped us, have a wonderful apartment in Madrid. It was beautifully designed and spotlessly clean with very nice light (even though it's a first floor) and a nice outdoor terrace space. Betina was so nice, very helpful and considerate of our arrival and departure times--it was really a pleasure to stay at their place for 3 days. It is in a great location--very central and easy to walk or metro to everything of interest (very much a genuine Madrid city neighborhood, and not a chic-y or too touristy area). Gracias Betina y Federico!
