We were very happy in Nino's apartment, it is located on a quiet and safe street but in a central area of Barrio Alto or very near from it, close to metro/train station to Belem and even to Sintra and close to a giant Mercado with exceptional Timeout food market. The stop of legendary tram 28 is very near. Nino was extremely helpful with tips where to go in Lisbon, he made sure that we will have a pleasant stay and we felt very welcome. I will recommend his place to everyone who wants to visit Lisbon.
