Diego is indeed a superhost. He was always very responsive to my many questions, especially regarding public transport. Also, he made us feel very welcome when we arrived. His place is just like the photos, stylish and very clean. And he provides all kinds of supplies which I wouldn't expect (e.g. shaving cream).
The apartment is in a great location to discover the city on foot. One of the best price/quality Airbnbs we have stayed at.
