Although I have not seen Pablo himself, he was very swift with answering any questions we had. He sent several e-mails when I first booked the apartment and the e-mails were really helpful to get around in Madrid. One thing you need to know, you need to pick up the keys to the apartment at the hostel in the second floor and the hostel reception does not speak any English. What you need to do is say "Pablo" clearly to the very polite ladies at the counter and you're set. Overall the apartment is really spacious, comfortable and at a great location. Best apartment I booked on AirBnB this year.
