Márcia's place was very centrally located in town; it is definitely bustling on the Flores street and pretty noisy both inside (thin walls) and outside (musicians, partiers, etc). The place itself was nice and very accommodating. I did appreciate the small kitchenette with water boiler. Had some trouble getting to the actual place by Uber, since you cannot drive on the street in front of the apartment complex. Overall, good stay, in a centrally located spot in Porto :)
