Joana’s place is amazing! We loved our stay and Joana herself was super helpful from the time we booked until we checked out at the end of our stay.
One thing to note is that because the apartment is on one of the most hopping streets in Porto, it can stay noisy until pretty late at night. We had a guy playing guitar and singing outside our window until almost midnight all three nights we were there. To us this was worth being right in the middle of everything, but it might be a bother to others expecting a quieter stay.
