We got a very pleasant stay in Porto and specially because of Marcia's place. The flat was really Nice and clean, the location is perfect and the huge terrace awesome except that there was 2 days of rain, everything was perfect.
Marcia has welcome us in person despite we arrived late (nearly 1am) and was a very friendly host from the beginning to the end ouf our stay.
As a bonus there is an excellent restaurant named "Tabua Rasa" were you can eat portugeses hams and cheeses with portugeses wine hold by two young and welcoming mens in the street just next to the appartement. This was our best moment in Porto :)
