If you're gonna visit Porto, you should stay this place.
This place is on the center of Unesco World Heritage district and its back door meets 9th century's street right away. You can walk to the river side within 1 min. Room was exactly same as I expected, the host was so sweet and kind. She explained briefly about city history with a city map marked some useful spots like supermarkets, restaurants when check-in.
Everything was perfect except no elevator but you know, "Unesco Word Heritage Sites" and "9th century's street"
Im willing to accept that. ;)
