Constantino's appartment is very nice and located in a restored old Porto style building. There is everyrhing you would need. You can reach center easily walking down the avenida, no need for cabs or public transportation. Constantino is fantastic host he welcomed me warmly and provided a lot of information about the city amd more, and marked interesting places on the map I've got from him. He also was there to wish me good flight on check out. Alrhough he said i can call any time if would I need something that was not in the appartment there was no need for that, all was perfect. Thank you Constantino!
