We spent 3 days in early September at Vasco's place. It was more than enough for two people (it could comfortably fit 4).  Advantages: very well equipped kitchen with all the utensils you might need; very clean and comfy; new and clean bathroom; nice soft double bed; a cheap restaurant opposite the street (Nicola's), that serves quite nice fish. A little bit on the downside: the windows look on the street, which was a bit noisy until midnight (beside the restaurant there's a little shop open until midnight opposite the street); the area between Intendente and Martim Moniz is a bit sketchy, if you want to go on foot we would recomend getting to town over the hill via Rua da Bampostinha (opposite the house). Getting to the center on foot either way takes about 10-15 minutes.  All in all, the advantages of the place absolutely outweigh these minor disadvantages.
