Edu was very helpful in kick-starting our visit of Porto, usefuls tips, a map etc.
The apartment is designed for airbnb guests and we liked its location because you're close enough to the city center (10 min of walking), however a little apart from the tourist pathways, which is great.
You can rent bicycles close by and cycle to the beaches.
The apartment was on the 1st floor and although the house was built rather recently you will notice visitors' footsteps above you, as they might prepare their departure during hours, where you would still like to sleep.
