Joana's (and her sister Ana's) apartment in Porto is beautiful! It's modern, beautifully (and very recently) renovated and well-appointed; bright and comfortable with 3 huge windows opening into the balcony. The sisters and their mother own a cafe around the corner (1 minute away) where they serve breakfast to guests--their coffee is excellent and the croissants are delicious! It's not deadly quiet at night, but you don't stay in the center of everything to hole up like a monk/nun and go to bed at 8PM. I was in Porto for work and did go to bed on the early side (around 11PM) every night and wasn't disturbed in my sleep at all--those big windows and shutters really do shut out any noise that might disturb rest. Ana, who manages the apartment, speaks English fluently; she is very friendly and generous with advice about great places to go that aren't totally overrun by tourists. I had a wonderful time and if I ever go back to Porto (and I hope I do), I'll stay here again if I can!
