We really enjoyed staying here. Mario was quick to respond to queries by email. Studio is exactly how it looks in the photos. Very central and handy location. The entire building is actually studios rented out by Mario, so when we arrived it was the receptionist who welcomed us and gave us tips. Our studio was on the third floor and there is no elevator - but all of Porto is full of hills and steps so best to get used to this early! The studio has everything you could ever need - coffee machine, wardrobe, plates, mugs etc. Plus some delicious port! Everything is very new and nicely decorated. Great shower. The only thing that could improve the studio is proper air con - there is a fan but this could be quite noisy if you needed it on all night during the height of summer. However, wouldn't let you put this off - it's a great place to stay and right in the centre of the historic part of the city.
