I didn't meet Siqi, but her communication was flawless throughout the whole trip. She was incredibly helpful and always very prompt with replies. Location was excellent, 5min walk to Canada Water tube station on the Jubilee Line, which is only a few stops away from all the big tourist attractions. Bed was a very comfortable double with no issues. The tenants in the house were quite helpful and let me use the kitchen and washing machine. Very quiet housemates.
The only thing was that because the housemates were tenants, they kept their individual provisions in their rooms. This included toilet paper, which couldn't be found in the bathroom. I've suggested to Siqi that AirBnB guests should have a roll provided and I'm sure this will happen.
Otherwise I enjoyed my week staying in this room, it was perfect for me.
