André's apartment was great. Super clean, very comfortable and warm, and a great location just across the metro bridge which we LOVED walking across to get to town and back. it was probably easier than staying in Porto itself!
our one complaint is the kitchen needs a bit more if you're going to cook at home (which we did a couple times), but it's a minor thing and most people would probably be perfectly fine with what is there.
ps. we drove up from our home near Lisbon. arrived on a Sat evening and parked right in front of the apartment. free parking all Sun then Mon am i moved the car to a parking garage just a few blocks up the road (10€/day). very easy and convenient - probably way more so than being in old town Porto.
