Nuno's place is extremely clean and spacious. It's located close to the subways and directly above a really good cafe. Towels are provided, but make sure to bring your own shower soap.
The walk to the downtown/Barrio Alto area is around 20 minutes. During the walk you'll pass several lovely kiosques where you can get a snack and drink. By staying outside of downtown/Barrio Alto, you get a much nicer and bigger space that's still within walking distance to all the city action.
Nuno was extremely easy to communicate with. He also put the extra effort in to help us store our luggage as we had quite a late check out. Would definitely stay here again!
