Clau's apartment is in an amazing location, with the ability to walk or transit to major attractions within the city. We loved the amount of street food, restaurants and cafes in the area. Subway and bus stations were very close to the apartment.
The apartment can be a bit noisy at times with dogs barking or other residents walking throughout. Had to keep the blinds down for privacy most of the time as the apartment is located in between two courtyards. As a heavy sleeper I had no issues but if you're a light sleeper you may not be as comfortable.
Overall a great spot.
