Just back from a 5-days stay in the apartment of Angel and Nacho. It's very well located, at walking distance to plaza Mayor, Sol, plaza Santa Ana, ... but there are also 2 metro stops nearby. The apartment was clean, spacious and so quiet. I only met Angel and Nacho on the last day and they are just great. Very helpful and happy to give you advise on all sort of things. Truly recommend staying here.
