Despite being adjacent to a busy road there wasn't too much road noise. Aircraft are prevalent, but seem to more or less cease late evening. The site its self is what you would expect, clean and tidy. Although we did feel it was a little cramped when busier. The location of the site is virtually perfect for visiting London. The only downside is the 45min bus ride each way. 1.5hrs on a bus, for a few days in a row starts to grate especially if you have kids. But given this is such a large city it would be unrealistic to expect anything better. Found the staff incredible friendly and helpful. So a big thank you to the staff. Expect to stay here next time we visit London.
