I've been in Ricardo's place for four days. At first, another guest was staying longer in my room so I had to be relocated in other room, which was the best room in the flat and what made my trip even more special!
Ricardo's flat in Barrio Alto is on of the best airbnb I've been. The flat itself was spotless, the views were incredible and Ricardo was really welcoming.
And also, I saw before going to Lisbon a lot of complains about the noise in the streets in that area, but in this flat you don't need to worry about it as it's really well located in a non principal street. 10/10
