The service was immaculate! We were welcomed so nice and friendly, we got a detailed description on the map where to find the best spots for every need. We could easily order a cheap transport service wich was reliable and came at 4 am to bring us to the airport. The location couldn't be any better, we were in the heart of Porto and no route we couldn't walk without any Taxi or something else. One point to criticize – it could be a little bit cleaner, it was clean, but my standards are a little bit higher, maybe too high for some people. Just saying it for the housework maniacs like me. I cannot give 4.5 stars, so unfortunately I had to give 'only' 4. But in resume I can highly recommend the apartment, it is so worth it! :-)
