Overall this was a very convenient apartment for our stay in Madrid. The location is fantastic with almost all the main sites within a 10-30 minute walk, and well connected to a few metro lines. There are tons of restaurants, bars within a few minutes, and the Mercado San Anton is just up the street. The street is lively but never noisy. While the flat is quite small and doesn't get much light (it's an interior apartment on the ground floor) with so many things to do nearby you most likely won't be staying indoors much! Ruth was very friendly, accommodating (she allowed us to check in super early in the morning and to check out late), and responded to all questions very quickly. She made our landing in Madrid super easy and comfortable.
