Stayed at Nuno's place for 3 weeks and it was just perfect!
Lived up to all the reviews, beautiful apartment, very accurate photos, clean and well kept, nice kitchen with everything that you need, comfortable beds, great shower pressure, lovely breezes through plenty of windows, gorgeous natural light, grocery store close by, quiet neighborhood that gives you a break from the crowds (with excellent restaurants), a tram or cab ride to center, but I enjoyed the 30 min walk to explore the city.
Nuno was very kind, responsive and helpful. I hope to visit and stay here again.
