This stay is highly recommended. My family of five stayed here and it really is an amazingly perfect location in the heart of the city. Right near plaza mayor, outside is active and lively, but inside the apartment is quiet and everyone slept. Nelson was a fantastic host. He communicated quickly in perfect English, which for us made it a bit easier. He responded super quickly. My one piece of advice not about this apartment: Driving in Madrid is not any worse than any other large major city, but parking may be worse. Don't drive if you don't have to but stay at Nelson's if you can. The apartment's in walking distance of just about everything. Highly recommended.
