Bill's place is a great deal for the price! He has an outstanding guide to help you with getting to his place and the area. From downtown Charring Cross train station located at Trafalgar Square, Blackheath is a 20 min train ride (£3.65 each way, trains are frequent) and 15 min walk to his house. It is an extra bedroom with no lock, he kindly let us use the kitchen and living room as well. We grabbed pizza and beer from the microbrewery 0 degrees which Bill had recommended, very delicious. For the price, this was a great deal!
