This is exactly what the AirBnB experience is all about. We could not speak more highly of Nuno and out stay in Lisbon. Nuno met us and immediately took us for coffee. During coffee Nuno pointed out all the places we needed to try and things to do. We did almost everything Nuno suggested and were not disappointed by any of them.
The apartment is located perfectly for exploring the city and the restaurants and cafes in the area are perfect.
We would definitely recommend this apartment and would stay here again when we next visit Lisbon.
One suggestion, get a taxi if you are arriving from the airport. It was a little difficult walking up the streets with our luggage (you will understand what I mean when you arrive).
