This is a lovely apartment. Small but comparable to most european apartments. The apartment is extremely secure which was great since i was traveling alone with my children on this trip. There are 3 separate doors of entry, each with a strong lock and corresponding key. Marga and her assistant were so accomodating and allowed us to check in earlier given our early arrival on an international flight. Apartment has everything you need and lovely balconies. The balconies while not facing the main street are still a lovely touch. There is some noise at night even though the balconies face the alley. THis likely is not normal, but probably more traffic given it was holy week when we were there. You walk right out of the apartment and it is near everything. Steps from both Puerta del Sol and Gran Via. Very near shopping and wonderful cafes and restaurants right outside the door front door of the building. There is a Police station right next door which was a plus as well. Walls are very thin, we heard neighbors on all sides depending on which room we were in -- i am sure they heard me yelling at my children as well lol! All in all a lovely apartment and perfect for our stay.
