My family and I had a nice stay at Amalia's apartment in Porto. The communication wasn't be a problem, we were understand all her indications.
The apartment was very clean and spacious. The kitchen is so big and equipped.
The metro, "Casa da Musica" is arround 5 minutes walking from the apartment, and most of the places you will want to visit are less than 10 minutes away on Porto's metro. No far away is the bus turistic stop, on Praça Maurizinho de Albuquerque.
We were enjoyet a lot on Porto, is very beautiful city!!

I recommend Amalia and her apartment highly!
