Wai-Yee and Tony are indeed fabulous hosts who are always readily available to help, in terms of the stay itself and generally about London as well. It's unlikely you'd feel bored in the apartment as they're sociable people who like to chat, especially if you could see yourself hanging out around the lounge and tv area.
The place itself has everything you would likely need for a long stay, is right next to a cafe, a stone's throw away from a Tesco, and conveniently situated to walk into the Canary Wharf CBD which also boasts a wide variety of shops including a largely sized Waitrose. It's also close to the promenade by the Westferry Circus. Transportation into Central London is easy and quick, making it a good base to explore the city and still be able to feel at home at the same time.
