Jonathan was very helpful to make our stay in London as pleasant as possible. When we booked he sent to us very detailed instructions about the flat and everything was as he said. He left food for us in the fridge for the first breakfast, which was very nice. The flat was perfect for a family of four (a couple and two children between 6 and 8). It seemed to have been painted recently and it had a microwave oven, two fridges, a dishwasher, a washing machine, a dryer, an iron and a hairdryer. WiFi worked perfect and TV as well.
I had to contact Jonathan by phone once and he solved my question on the fly. He also answered promptly all the emails that I sent him during that week.
