We arrived rather late in Porto but Kurt and Teresa were great hosts, very welcoming and friendly. They even provided some bread, butter and cheese for breakfast. We used the shuttle bus booked via ryanair which was perfect, cheap and really effective (20min drive from the airport to the city centre, drop off point is literally around the corner from the flat). We stayed for 4 nights and had a fantastic time. The spacious and beautiful flat is right at the heart of the city and you can easily walk everywhere. To our delight Porto now has some really good vegan/vegetarian restaurants and we highly recommend a fine dining experience at 'Essência' (short ride on the metro but worth it) and 'daTerra' (Baixa, 7min walk from the flat) which serves the most amazing buffet.
