Carla is a great host who always replied swiftly. Her apartment is located in a quiet area and at a short walking distance to the historic city centre of Porto and the Douro river. The apartment is sparkly clean, very comfortable and beautifully decorated with stylish and simple design. There is a supermarket, bus stops and tranway stop at 5 minute walk. We loved buying foods from local independant groceries though. We booked a free walking tours in the city of Porto, and it was really worth it. The tour guide is very knowledgeable about the history of Porto and recommended us non touristic restaurants and places to visit. It is worth booking a day trip to the Douro Valley, if you want to know more about the Port wine making process and its history behind it. Porto is a beautiful city boasting amazing architecture styles - Gothic, Baroque, Renaissance, Romanesque and Art deco. We really enjoyed our stay at Carla's place.
