I highly recommend this studio apartment. It's in a great location, slightly off the tourist trail but an easy walk to all the parts of Porto you'll want to see, especiallythe Ribeira, Sao Bento and Bolhao districts. There are lots of places on your doorstep to eat, drink and buy groceries, including an amazing pizzeria in front and a street behind the building with friendly bars and places to eat that attract huge crowds to watch the sun set. The building is quite handsome, with a wide, gradual staircase that's not too steep. Most of the building seems to be holiday rentals, so you don't feel you're annoying the neighbours. The apartment itself is very well equipped and quite spacious. The terrace is huge and enjoys amazing views. Raul was very friendly and helpful from the very beginning. He helped me work out the reservation system for the car park next to the apartment. Check in was very smooth with very clear instructions. Porto is a great city and Raul's apartment is the perfect base to explore it from.
