The location of the apartment was so great that we never used the transportation system. All of the major areas take place at the walking distance. The flat was clean and quite modern. Kitchen has all of the basic materials you need to cook. It is the only problem that apartment was a little bit cold and heaters were not sufficient. We could not meet with Teresa, but meeting with Kiki was a real pleasure. She brought us a map and explained all of the "must" places, directions and restaurants etc. She was really kind, helpful and lovely. I am sure that if i visit Porto again, Kiki&Teresa's apartment would be my first choice. So, do not hesitate to stay at their place!
