Boris was a great host! The apartment that we were supposed to rent from him was having a few problems before we arrived so Boris offered us one of his bigger apartments in Shepard's Bush for no extra charge at all...this place was more than twice the size of the place I orginally booked!
The location was great and it was very easy to get around London with the apartment being very close to two train stations.
I highly recommend Boris as a host. He was friendly and very helpful.
