The apartment is in a good location close to the metro and is easy to walk everywhere from it. The furthest point of Barrio Alto took us about 30 mins to walk to which isn't bad at all if you don't mind walking. The apartment is clean and is exactly to the pictures on airbnb. The only call out is that you can hear a lot of sound from the corridor, upstairs apartment and next door with the construction at around 8am. So if you're a light sleeper or enjoy a sleep in, you need to be mindful of this. I didn't get to meet Nuno or Andre unlike other reviewers but both are very prompt with responding to your questions. Overall I enjoyed my stay at this apartment.
