I stayed here for one night in early May. Checkin via Joaquin's friend was very straightforward and friendly. The apartment was bright and spacious, with all the necessary facilities. Good location within 5-10 minutes walk from cathedral, and plenty of local bars/restaurants to choose from.
The only real drawback for me was the noise from the street and neighbouring apartments in the evenings. Clearly the walls are pretty thin which made having a good night's sleep difficult for someone like me. Would suggest earplugs.
Otherwise a perfectly adequate apartment for 1 or 2 people.
