Nuno's place is perfectly located just next to Picoas metro station in Lisbon. It is close to the main road with lots of traffic, but surprisingly it was not loud, which was my concern before.
The apartment is not big but would be perfect choice for two persons and it is well-equipped, AC and wifi worked smoothly. It has huge windows, so very light, and it also has a small balcony, which is nice if you want to have a breakfast there in the sunshine.
I would recommend this place if you plan to visit Lisbon.
