The appartment was like expected very well situated: very close to the subway stations (Trindade and Bolhao), so that we could move in Porto with all subway lines. But in fact, as the appartment is around 2mn from santa catalina street and the famous "majestic cafe", 1mn from the Bolhao market, 10mn away from the Douro river, same for the historical center of Porto we finally walked in the city. In the morning there is a very good pastelaria almost in front of the appartment with hand made pastries. We could drink a coffee and taste one or more pastries of Portugal and also speak french with one of the waiter, so nice with us!
The appartment itself was very clean, everything needed was inside (towels, iron, wifi...). Our hosts was really punctual even though we arrived a little earlier than expected. He gave us good advises to visit the city and gave rapid answers to our questions by mail. The only weakness of the place if I have to tell one is it is at a second floor without elevator. But if you want to visit Porto it is better to like stairs and heights!
