Marta's place is a lovely one, it is very clean and nicely decorated. It is sunny, because of the two windows that come straight to the balcony. It is conveniently located, you can easily find supermarket, restaurants, subway is also not far away.
Marta is a great host, she gave me very useful instructions about the Porto.
It was a pleasure to stay there, I'll certainly choose this listing next time I'm in Porto!
