Filipa was an amazing hostess, answering any and all questions I had about logistics, history or recommendations.
Bus access to the center is simple and not too far (10-20 min, once you're on the bus), and you can also walk to the center (around 45 min), if you don't mind a few hills.
The flat is well-equipped and clean. I was given my own space in the refrigerator and pantry. The room can get a bit cool in winter, but there's a heater available if needed.
I'd highly recommend Filipa's place for a cost-efficient room with fantastic hospitality.
