Luxury, convenience, great service and communication describes my 5 star experience at this flat in Porto. Maria offered a private driver to pick me up from the airport and Carlos was amazing. He took me and my luggage straight to the flat (which is up a steep incline where cars cannot go) and made sure I had all the info I needed, and we made arrangements for him to grab my luggage, keep it until my bus, then pick me up and take me to the station when I left. Amazing service and such a pleasant person.
Porto is an elegant and historic wine lovers town and you want to see as much as you can but bring good walking shoes with tread because when it rains, as it did 3 out of my 4 day there, the steep cobblestones streets are very slick. I did an informative private tour from a car which was fabulous on my first full day, then gravitated towards Foz do Douro, where the Douro River feeds into the Atlantic. Its a 15 min/$7 Uber ride or you can take the tram from the Cathedral area
