If you are planning a trip to Lisbon do not hesitate to book Goncalo and Diogo's flat if it is free. The location is excellent, we were able to walk to all main areas of the city from our base as it is right in centre. The communication in advance of arriving was exvellent and responsive, helping us with planning and directions. Claudia was very helpful at check-in, giving us lots of helpful local information and making sure we could use the entry codes for the flat. The flat is clean, comfortable, and well equipped for a stay in this beautiful city. We loved it.
