The apartment is in a great location in Barrio Alto. Walking distance to tons of shops and restaurants. It's also clean, and has lots of natural light in the living room. The check in was smooth and Miguel was very helpful.
The only downside, as others commented, is that it's located right above a bar which (at least during the weekends) blasts music from midnight to 3am, plus there's another bar right around the corner. To be fair, I arrived on Halloween -so parties seemed to be louder than usual- and stayed through the weekend.
