The stay in Carla's apartment was a pleasure. It is a very clean and cozy apartment near the main shopping street. Unfortunately due to construction work the trafic was redirected through the street in front of the apartment, making it a bit noisy. Carla and her husband are very accommodating and have given nice hints to interesting things in Porto. If I come back to Porto, I would be pleased to stay in the apartment again. A big thank you to Carla and Carlos!
