We enjoyed our stay in Cerasela's place very much. The house is large with plenty of rooms and multiple bathrooms to accommodate a group of seven persons as we were. The house was very clean and it was really a pleasure to have rest there after our busy days in central London. Cerasela is superfast in communicating and is very helpful indeed. The only little down side there is that the nearest overground train station is about 15 mins of walking distance so you need to combine your journey plannings with buses if you want to avoid that. Nevertheless, with googIe maps and with the quality of London's transportation system this is not a big deal.
Overall, this a highly recommended and exceptional place to stay!
