Gergely's apartament was super amazing. It's not in a Porto center, but it was for us a big plus, as we could rest from the crowd. I totally recommend to go by the beach and to watch the birds as there's a lovely view on the birds natural park and also on the bridge and on the sea. I also recommend walking through Vila Nova Gaia to Porto, take a little hike and you'll see really nice vilages and great places to eat or drink coffee :) the bus stop is right next to the building so all is easy to go to Porto and come back as the buses are going there until late night. All was clean, Gergely came to us with a map etc and he was on our alarm all the time we would need. Great to meet you Gergely!
