The hosts were very nice during our communication through airbnb and Rui's sister met me upon my arrival and answered all the questions about the city, what to see and where to go and recommended some nice Fado places. Though it's not a problem to find a restaurant with Fado in the area, the apartment is surrounded by so many of them and all are very nice! Also a bottle of wine and fruits were waiting for me, which was very pleasant :)
The apartment is rather small, but it was perfect for me traveling alone, and it's really clean and cozy, with a big comfortable bed and the windows going to the Tejo river. The district is very lively, you really get to feel the life of locals there :)
In all, it was a great experience and I'd recommend this apartment!
