Rahyan was a great communicator & this is definitely one of the cheapest accomodations near London with a "parking spot". Be aware that the free parking is only available from 4pm-10am. We parked at the Stratford International Car Park which was decently cheap for the day.
The listening says "no smoking", but at least for the night we were there the unit smelled heavily of cigarette smoke. My partner & I both had irritated throats in the morning. Not sure if this was just a case of the people before us breaking the rules or if it was the surrounding environment. But if you're sensitive to that, this was our experience.
