The condo was very nice. Very clean and we were met with a glass of Port. We were there in Oct. and had no need for AC or Heat, so I cannot comment on that. The only negative was the dog next door was a little noisy at night-during the day was not a problem for us, but kind of loud at night. Please be aware that if you are not "hill walkers" you will need to use public transportation or a taxi to get most places. Teresa was very helpful in arranging transportation back to airport at the end of our stay. She was fantastic at communicating if there are any issues or you have a question. She left plenty of sightseeing brochures and maps for us to use.
We will be back if we get to Porto again.
