We enjoyed staing at Nuno´s place a lot. The cozy house offered all things for the daily use we needed and is located in a quiet and non touristic area - at the same it is pretty near to main places, you can reach Avenida da Liberdade, Praca Rossio, Bairro Alto, Príncipe Real by walk within ~15 minutes. Also you have little distances to metro stations Rato, São Bento and the train station Cais do Sodré. Further you have some small supermercados in your neighbourhood (next only 100 metres away), which makes self-service in the house very easy.
Moreover the contact with Nuno was very friendly, he is very responsive and helpful.
All in all to us discovering lisboa while staying at this place was great.
