A fabulous place to visit and explore.
Our time in Porto was wonderful and made even better by staying in a beautiful self-catering apartment, called Oporto Platinum Loft. I couldn't recommend it more highly.
You do need to be physically able as there are stairs to climb and it is on a steep street.
You can read all about our time in Porto in my Facebook pages (No. 2 and No. 3) which will also give you recommendations of where to visit and what to see. Pre-booking places is essential before you leave home!
