It was very nice to stay a week in an apartment of Lisa. Everything was fine, our late check-in was not a problem. We got a lot of tips what is worth visiting in Porto and Lisa offered us her help, if we have any problems or questions. For those who come by car - the parking on the street is paid between 09:00 and 19:00 but it's not very difficult to find a place. I regret that we couldn't stay longer in Porto and I hope we'll come back there one day! :)
