Don't think, just book! This apt is in a lovely location - 5 minute walk to plaza mayor and 2 minutes from the metro. The apt itself is beautiful - you can tell its newly renovated and they really put in the time and effort to make it pop. It's also quite spacious - comfortable for 3 people to stay.
Marta was also very responsive and responded right away when I had any questions throughout my stay. Thanks again!
