Marga's place was wonderful for our three night stay in Madrid. Elena who helped us check in was very nice and gave us guidance on how to explore Madrid and Spain. You really cannot get more central than Marga's apartment which is right in the middle of the action. The apartment itself is very wonderfully decorated, clean and spacious. All of the key sights and restaurants are within walking distance which was super convenient. As other reviews have noted, it does get noisy at night, which might be a problem for light sleepers. We did not have any issues sleeping at all, though. Would recommend Marga's place for a comfortable and convenient stay!
