I had a great time staying in José's flat. It is very well located, close to Santa Catarina street, Bolhao market, Aliados, and many other tourist attractions. Bolhao metro station is a short walk from the flat too. The flat is very nicely decorated, very clean and with a fully equipped kitchen, comfortable bed, and a really nice shower. Despite being in the city centre the street where the flat is very quiet at night so I didn't have any problems with noise. José is a wonderful host, he was there to welcome me and show me the flat, he left some treats like water, juice and fruits which was really nice. I totally recommend Maestro apartment to anyone that wants to stay central in order to better enjoy this beautiful city that is Porto :)
