Filipa's place is very nice. It is in a prime location allowing access to sights in any direction we leave, literally any direction, located in a narrow alley but no residents opposite (deserted house with bricked windows) so privacy is no concern even with open shades. We loved the mixed habitants of connected streets from purple faced lady shouting with her kids and relatives (far enough from the flat to be audible inside) to stylish young shoppers, with mixed matching facilities like I. World War style moustache wearing owner in his grocery, modern accessories shops and restaurants for workers to gourmets. We had the feeling we saw "real" Porto. Not to forget Filipa's own sandwich restaurant (must try!). Not crowded at all, moderate traffic, there are more high profile streets elsewhere but all in all the area was for us.
We managed to heat up the place quickly and make simple food (the equipment is basic but enough for couple of days, only the lack of some light at kitchen desk made things difficult, that should be installed, some simple led strip would do). The internet is quick and stable. The upstairs bedroom has a small balcony with gorgeous view (and crying seagulls). We slept well and had a good time.
Filipa is kind and helpful, also makes delicious sandwiches - cannot emphasise enough that you should try out her little restaurant. We loved staying at Filipa's place, 100% recommended.
