Marja's place was fantastic. Absolutely stunning views of the river, large space, and plenty of lighting. The apartment was close to many things and you can walk pretty much anywhere (though lots of it will be uphill!). Marja was also very responsive and attentive to any questions we had, which was wonderful. Our only issue was that the hot water ran out very quickly, but as long as you take fast showers, it wasn't a hinderance. I would absolutely recommend Marja's place for those who want to explore Porto.
