Nader's apartment was really nice and the location was extremely central to numerous tapas joints, shopping, supermarkets, metro and cercania underground lines. It took us a minute to figure out that there's two separate underground systems. The cercania system extends out to the suburbs and will get you close the the apartment as well at the Sol stop. Nader was able to schedule his friend Jose to pick us up at the airport. Jose was there when we arrived, even though our flight was way late. Jose was very friendly and gave us a vast amount of information on the way to the apartment.
Once we arrived, Nader was outside waiting for us. He was very welcoming and showed us everything we needed about the apartment, gave us his cell in case we had any questions. Your US cell will work in English as if you never left the US, that goes for all apps like Google maps, yelp etc. Also, even though some numbers like Jose's start with 0, I dialed him at the airport and it worked fine. Helps if you have T-mobile, as international service is included in most of their plans. The apartment its self is even nicer than appears in the pics. It's very modetn and looks like it's brand new. Our stay in Madrid was way too short. We found the general vibe of the population very chill and friendly. There was even a really nice lap pool nearby. Nader, you for everything we hope to see you in the future!
