This is an overall very good apartment. The price is more than fair considering the excellent location that is seemingly near everything important in the center of Porto. The space is small but never feels cramped, is nicely decorated and was very clean. The only issue we had was the sofa bed which was overall uncomfortable, making it hard to sleep well. The key collection area was about 10 mins uphill from the apartment but this was not an issue, as it is pretty close. Would probably consider staying again and with a more comfortable bed wouldn't hesitate.
