Well-located and cozy apartment, and friendly host. It's quite comfortable.
Cedofeita is an interesting area, with lots of nice shops and restaurants. Try Capim Dourado for authentic Brazilian--excellent bobó de camarão.
Do note: Like most places in Porto, the apartment has no heating, only a space heater. This was sufficient for April nights, but might not be for January/February. Also, the hot water tank is small, so be careful when showering.
