Overall, Rob's place is a good value for the money I paid for 5 days of being there. The room was large and the house is safely protected with multiple locked doors. There are bus stops very close to the house and it's fairly easy to commute to major locations. The host is very responsive and is there to provide excellent customer service.
Some downsides were that heating worked only at certain hours and it was cold sometimes (especially in the bathrooms) but maybe it's the case in many places in the UK. In addition, there aren't very many grocery stores nearby.
