Marga’s place is in a great location, right by Puerta del Sol. There’s a metro station right there you can hop anywhere to and places to shop and grab dinner. It is very noisy because it’s located so close to the center, but we knew that when we booked it, although it is noisy throughout the entire night to the next morning, and that was somewhat unexpected, so this may be troublesome if you need the quiet to sleep. We were woken quite a few times. I’d book this place again though because of the convenience of the area.
