I just returned from long holiday in the UK, France and Germany. I had the pleasure to stay at Raul & Carol's place for a week. Its a great location with easy access to two tube stations, though we primarily used Oval. The apartment was spacious and clean, although a previous guest smoked heavily in the living room and it was noticeable on arrival. There were plenty of amenities like extra towels and pillows and kitchen was well stocked with utensils, dishes and glasses. I loved having access to a washing machine/dryer. That was so convenient to wash clothes before leaving for the next part of my trip. My only suggestions would be a new drying rack, we couldn't get the current one to stand up.
Communication with Raul & Carol was very good and they were helpful in allowing us access to the apartment a little earlier than check-in time so that we could drop off luggage. We had several communications with them throughout our stay as well.
I highly recommend Raul & Carol's place.
