The flat is very central. The Zero hotel across the road has a great bar with sofas and a good dj. There are lots of very nice cafes with great interiors all over Porto (Cafe Magestic is overrated, don't bother- it's the next street over). Sushi San had gorgeous sushi. Porto is so cheap for coffee and wine. It's a busy city with noise from construction and traffic and crowds and very hilly-everyone was in runners. People are extremely friendly and helpful. I enjoyed my visit.
