Above all, the location of Maria's apartment is it's greatest feature. It is literally a two minute walk from the Plaza Mayor, and a four minute walk to the Palacio Real and the Almudena Cathedral. One thing that was lacking was Wi-Fi. For us, this wasn't a huge problem, as our stay was only two nights and the extremely nearby San Miguel Market had a free public connection that we used for posting photos and communication, while also enjoying some sangria. Still, if this is important to you, plan accordingly. We would definitely stay with Maria again.
