Ollie's place is a bit out of the way from London, but a few mile walk from 2 different train stations. He communicated fairly well considering I was hunting for wifi in order to message him, but we never got a chance to actually meet him.
The space is accurately described in his listing. It was not the cleanest by any means, but certainly not dirty. Had all the necessary amenities. Overall I would recommend it, but it can get a bit expensive taking the train in and out of the city, so if you don't want to spend ~£15 getting into town quickly (we never took the bus, so no input there) maybe look for something closer.
