Nuno was simply a great host. He met us upon arrival and was super generous with his time in giving us excellent "locals only" tips. On our last day, a few hours before our flight, we accidentally locked ourselves out; however, Nuno was able to get a spare key to us in just a few minutes!
The studio itself is well located in the heart of Barrio Alto, and has all the basics that you need for a comfortable short stay.
We'd do it again!
