This is a great place if you want to be right at the market place on Portobello! You can watch the market setup from the window. The host runs the airbnb very professionally, with the little extras of shampoo, flipflops and a very clean space. The generous share of things to eat in the kitchen, such as cornflakes or misosoup is great too.
If you are sensitive to traffic sounds, then this place is not recommended, as it is close to a heavily trafficed overpass and you will here trucks etc throughout the night, especially if you want to open window for some outside air.
