We had a perfect stay in this apartment as 3 adults and 3 children. The check in process was easy, the owner was easy to reach, and the location was just perfect. It was our first stay in Madrid so I was a little nervous about picking the right neighborhood and what the place would look like upon arrival, but I was relieved to see this gorgeous place was ours for a few days and with easy walking access to such great highlights of the city, and a short walk to the bus stop to go a bit further to Retiro Park and Prado. I saw some reviews mention noise but we didn't have a problem with it at all, from neighbors or nearby bars/restaurants. Just my own kids :)
I'd definitely recommend this apartment to groups, families, or anyone looking for a clean, updated, and well located place in Madrid.
