My husband and I stayed in Gary's flat for 5 days during a trip through Europe.
This flat has everything you need! It's incredibly clean, well put together, and the kitchen is nicely stocked. It's a bit of a walk to get to the train station, but we didn't mind.
Gary is very nice and even picked us up from the train station. He promptly answered any questions I had before and during our stay.
If you want somewhere to stay that is out of the bustle of London center, but still close, then this is the flat for you.
