I stayed at Gavin's place for a week long stay in London. We loved the location, allowing us to walk the city to visit all the major attractions. We loved the SOHO neighborhood and we were just down the street from the theater playing Harry Potter.
As everyone has stated in previous reviews, the apartment is located on a busy street and it get's very loud outside on weekends. We didn't mind the noise at all, but if you are a light sleeper, noise cancelling headphones are a tremendous help.
Can't wait to come back to London and visit again!
