The flat was very comfortable and located well for transport links. There are shops and food outlets nearby, all within walking distance.
Crystal was excellent with her communication, and her father was a delightful host when he welcomed me to the flat. Both my boys and I were made to feel very welcome.
There were a few small issues that crept up that were not the fault of Crystal at all but they were rectified almost immediately which made our stay much easier.
I felt the price, for London, was quite competitive as well.
