The flat is fantastic, very clean and well located. Perfect if you want to go out to the many bars of Bairro Alto, and to lots of nice eateries. The tram 28 is about 2 mins away, metro 5 min walk. THe neighbourhood couldn't be more convenient. Pedro was very generous and let us stay longer on our day of departure as our flight was late in the evening.
Unfortunately the lack of natural light in the flat makes it very dark. There are only to little rectangles in the main door (which leads directly into the living room) but which open directly to the sidewalk, meaning everyone can look in. More importantly they are too small to be effective. You always have to switch on the light when in. THere are narrow glass doors in the kitchen and bedroom, that lead to the tiny courtyard but do not draw any light into the main living area either. I'd more than happily recommend Pedro and his flat if you're happy with the non-natural light during the day. The flat is otherwise great.
