We enjoyed our stay at Nunos home very much. The apartment is in a really fabulous style, the kitchen very well equiped. Nuno was always helpful and available, 5 extra stars for him!
The only thing you should really keep in mind, when you decide to stay there: There a some bars in the street, directly under the house. Bairro Alto is famous for parties, people are partying all night long with loud singing until 5.... so if you have problems with sleeping in noisy atmosphere, be aware! We slept well, really. But it ist definitely loud.
