We had an experience here which did not reflect the many positive reviews. There was a heatwave in Porto the week we stayed with temps in the high 90s. I knew we would not have air conditioning but what I did not know is that leaving the windows open would mean being devoured by mosquitos. Joao warned us not to have the windows open but it was so very hot by 3am we got desperate and opened them. By morning we all had dozens of bites. My 3-year-old had 24 bites and her misery ruined our stay in Porto. Now, I in no way blame Joao for heat or mosquitos, those are natural forces. But I do firmly believe this unit needs AC. It was beyond miserable and what’s the point of staying here if you have to shut all the windows/ shutters? The view is the magic of this place. If AC is not feasible then more fans are needed. He only supplied one small fan. The place itself is accessible via many steps as others have said. It was difficult for us with kids and luggage but that was our fault. The view is mind-blowing and Joao is nice and helpful. But if you’re coming during the hottest time of year I would look elsewhere.
