My girlfriend and I stayed in Abigaíl and Miguel's place for three nights during our trip to Porto and we couldn't recommend it enough.The location is great and close to lots of restaurants, bars and bakeries from which you can sample the city's great cuisine. All of the main tourist attractions are within walking distance and the city's main metro station is only 10 minutes away - this made travel to and from the airport very easy. The apartment itself was immaculately clean and there was some very nice tea and coffee provided. In the evening it can get a little noisy as the apartment is near to some popular night spots but this didn't particularly bother us. Overall we has a great stay and would definitely come back if we're ever in Porto again!
