Teresa was really helpful and everything went smoothly. The flat is really nice, bright and sunny and in a quiet neighbourhood. It is very well located, perfect for visiting all the interesting sites in Porto. You don't need a car, as you can do everything either by foot, bicycle or public transport. Teresa gave us all the necessary information to explore Porto and we were welcomed with muffins and fruit juice and the local porto wine. We felt very much at home and would have loved to stay a bit longer. Teresa and her husband were also very understanding in letting us leave our luggage in the flat before we left for the airport. I would definitely recommend staying in Teresa's flat.
