We have had a couple of nice days in Marthas fantastic apartment in Porto. The apartment is placed a few streets away from the more touristic areas, close to public transportation and thus easy to go to. The flat is in two floors placed at the fourth floor with no elevator, but the stairwell is wide and easily accesible. We were welcomed by Marthas aunt, a very friendly lady, who told us everything needed. There is also a book with plenty of tips for good restaurants and must sees in Porto, which is very helpfull.
