Porto is an awesome city. And the apartment is bright, spacious and centrally located to everything you want to do in town - which is a great perk.
The drawback is that the apartment alley is a hub of vagrant activity. There is a steady stream of homeless campers and alley drinkers directly below the bedroom window basically around the clock. We got sick of pushing past the riff raft to get to the apartment door in the evenings and by night six of listening to them carousing right below the bedroom window we were eager to head to Lisbon.
