Me, my boyfriend and a friend of us spent the weekend in Porto and stayed at KiKi&Teresa's place.
The house is tiny and perfect for a weekend in town. The location is great, walking distance to the old city center and quite overnight.
We arrived quite late (around 1am) and we were kindly welcomed in the house and showned all the facilities. We have been provided with a detailed map of the city and we we got suggestion on places where to eat (specially vgetarian -highly appreciated) and hang out.
We recommend to stay at Kiki &Teresa's place.
