It was my 8th time visiting Lisbon, and so far this airbnb is the best I have stayed in. The biggest plus is the value you get for this money: it's central, but yet on a calm street, renovated and the price is very affordable - I stayed for 3 weeks in comparison to, for example, Paris(where I have been for a week this summer) - I payed nothing for Lisbon.
Highly recommended this option to anyone thinking about visiting Lisbon!
