Gee's home is conveniently located by the tube and cable cars and is only about an hour away from Heathrow by public transportation. There's also a really nice park by the water nearby. Across the street, there is a convenience store that you can stop by if you run out of something or just need a snack.
Gee and her family were such wonderful hosts, respectful, and very accommodating! My flight was late, so she stayed up until 01:00 for me to arrive, and my roommate for the trip wasn't able to arrive until the next day. She was also very responsive (usually within a few minutes) and helpful. Added bonus: there's an adorable puppy!
The house is extremely clean, and the bedroom was very cozy. The bed, sheets, pillows etc., were really comfortable! There's also a loft-bed with a small work area underneath, and we found that there was plenty of space for two people to work at. One thing to note is that the door doesn't seem to have a latch/deadbolt; I didn't find it to be a problem since the door never opened on its own.
I would highly recommend this airbnb for anyone on a budget and interested in staying at the O2 area.
