The hosts were absolutely amazing! On my last morning, I had to take the National Express to Luton and the host drove me to the closest bus station (seeing as the busses were not running at 05.00 in the morning). They made me feel extremely welcomed, and their description online perfectly matched the accommodation. In addition, the neighborhood was fine and I felt extremely safe (they have a security system). I was only in London for three days, attending a conference at Wembley Arena. This location is PERFECT - you literally walk out the door, hop on the bus, and it takes you directly to Wembley.
