I stayed for a week at Ong's place both for work and leisure, and can really recommend it. The place is great value for money, with a beautiful view, close to the city, and just walking from the tube to the flat gives you a good sense of Chinatown - plus tons of options to eat. Ong was very helpful with directions etc ahead of arrival - I havent actually met her in person, but Elle was always available and very lovely. Highly recommend the place!
