We stayed 3 nights in Joao & Rita 's flat, which is exactly like the picture, very well decorated and clean ! We did not meet them, but we had a great welcoming by one of the manager of the flat.
We appreciated that everything you need is there, some coffee, tea and tips for restaurants :)
The flat is well located in the heart of Alfama, (closed to Santa Apolonia metro station as well as a public parking not expensive !!) Because of this location, it is a bit noisy ( if the window is open and also we heard the noise / people from the stairwell when your are in the bedroom)
Anyway, it was a great AIRBNB experience to discover this lovely city : Lisbon ! We recommend !!!
