The Fabio was very helpful and warmhearted host. The building is typical London house - a little shabby, cosy and had a great vybe. Though on our arrival in the midle of december temperature outside was below zero and the heating in the building wasnt very efective - but Fabio provided aditional heater.
Central location (Kensington) alouds to explore the city on foot, the metro station is just outside the place.
Its not cheap for what you get - but I quess its moderate central London price and definately cheaper than a cheapest hotel in this area.
