It was nice staying at Susettes house. Our child had an own room what we found nice. Kitchen has almost everything you need for a couple of days to cook.
Check-in was easy and we got a lot of information by Jorge (Susettes husband) a few days before we arrived. We loved the Boxspring-beds. It is not super quiet at night where the house is but compared to houses in Porto it is a quiet nighboorhood. There was a dog barking sometimes, the garbage can close by was drained at night and in the morning you could hear the airplanes. But anyway I had a good sleep.
Vila Nova de Gaia is not Porto, but a nice district where you can find a lots of portwine cellars. You need a 20 min walk to get to the food of bridge Ponte Dom Luis I.
What nobody told me is, that Porto hast many streets with very steep rises/climbs. Sometimes you needed to push the baby carriage 1 km up the streets across cobblestones. ;-)
