Mark is a great host, he even picked us up from the bus station after our flight was delayed. He answers quickly to questions and provided us with some breakfast essentials like coffee, bread and tea. The flat is in a nice, quiet street but near to pubs, bus or grocery stores, so a great base to explore London. The flat is big enough for four people and the watertank holds enough hot water for all of them to take a shower. There's a TV if you are bored, a washing machine and a dryer if you need to wash. The only drawback was the cleanliness of the kitchen, which was a bit greasy from cooking, but it was nothing we couldn't deal with. All in all I greatly recommend Marks's place!!
