The apartment is located in the perfect area, very close from restaurants and bars but not noisy as it's not in the center of Bairro Alto. I didn't need to spend much money for the transportation as it's walking distance from Baixa, Chiado, and other busy area.
Nuno was very friendly and nice and always offered help whenever I needed. He gave me names of some nice restaurants and showed me direction. I was lucky as a girl who stayed at his place at the same time was really nice too and she helped me when I had a trouble as well.
The room is simple, clean and big enough for myself.
I would like to stay at Nuno's place again when I visit Lisbon again.
