Pros:
The location is great. It's pretty much on the river, next to a park, a stone's throw from Imperial Wharf station, and above some good restaurants etc. It suited my requirements pretty well in that regard as I was staying in order to attend a course just by the station.
I didn't meet Georgia as she was in Spain but she was very helpful on the phone and responded quickly to problems. Georgia's flatmate Greg was nice and friendly too. The balcony is nice and big. The kitchen and ensuite bathroom have beautiful granite worktops. Georgia had left some toiletries for me, which was very sweet of her.

Cons:
The cleaner had let Georgia down so when I arrived the bed wasn't made and the ensuite bathroom hadn't been cleaned. This was rectified pretty quickly though.
For such a swanky neighbourhood and building, the flat has a studenty feel about it. The carpet in Georgia's room badly needs replacing. It used to be white/cream but is mainly grey/black. The sofa in the living room is also covered in stains (these things don't show on the photos). The towels left out for me were also stained (they were washed, but were pretty old). The whole place badly needs repainting - the wall and ceiling in the ensuite are peeling quite a lot. I guess the landlord isn't very responsive about maintenance. I didn't mention these things to Georgia during the stay because I felt that there wouldn't have been anything that she could have done about them. I mention them here so that future guests know what to expect. I was disappointed with the overall standard of the place, given that my stay (11 nights) cost over £1100. That said, I realise that in this area, you are really paying for the location, which, as I've said above, is totally great.
