What a great place to stay in Madrid! This apartment is right in the middle of where you want to be in Madrid. We stayed for just 2 days, but it is literally a 20 minute walk or less to everything, and most likely less than 10 minutes to most places that will be on your list. We only met Esti for a brief moment when we arrived, but she was very friendly, and her apartment is very quaint and clean. It is up 6 flights of stairs though, so be prepared for some exercise every time you leave! It was nice to find a bottle of wine waiting for us when we finally got in though!! Overall, a very nice experience, and we would gladly stay in Esti's apartment again if we make it to Madrid!
