Gundega and Antonio's place is wonderful. It's in a great part of town close to some cool bars and good places to eat and slightly away from the touristy centre (which is still only a short walk away). The balcony is a really beautiful place to sit (plan an extra day in town just to hang out on the balcony!) and Gundega and Antonio gave us great tips for things to see and do in Porto. I highly recommend and hope to be able to stay again some time.
