The location of the apartment is just perfect and a short walk from Graça, where we spent most of our time, as well as the inner city. There is also a small balcony with a nice view but not big enough that you could sit out there in winter. Nonetheless, it was pleasant and we really enjoyed the ease of coming home at night. If you are sensitive to noise, I'm not sure there is anywhere you could stay in Lisbon but definitely not here as it is on the street.
The apartment unfortunately does need a bit of a facelift, so we tried to stay outside during the day rather than come home for lunches or even drinks, which we would have preferred. Above all, the bathroom is run down with no ventilation and a leaking shower. Beyond that, there were cosmetic things that could be improved i.e. swapping out the sheets, blankets, cushions etc., some of which were a little dirty.
We are leaving 3-stars because the experience was not unpleasant, just some work needs to be done inside the apartment. We had the impression that a lot of buildings in Lisbon needed some TLC so perhaps Filipa's is actually one of the better apartments- who knows!
Check-in and out were easy.
