great apartment in an amazing location. plaza mayor and mercado san miguel is less than 5 minutes walk away. palacio real also walkable. two metro stops on different lines within walking distance. the area is also great for eating and drinking - better prices, vibe and quality than directly in and around plaza mayor. the check in and out was effortless and the apartment was spotless. the wifi is fast and some comforts, like Netflix and coffee pods, make the place super special.
the only downside, and only if you're a light sleeper, is that both bedrooms have some noise. the one looks onto the street with a tavern downstairs and the other to an inner shaft/small courtyard space where you can hear water gushing down the drains and other tenants talking. but the windows are quite soundproof and there are fans and aircon, so it depends on whether you need fresh air :).
would definately recommend.
