Mary's place is in a great location, very convenient. She is also a friendly and happy host. When I embarrassingly locked myself into an area near the flat, she was quick and happy to help me find my way out despite the late hour, which demonstrates her positive attitude and hospitality. (And, so you know, if you follow her directions, you won't get lost. I thought I knew the way on my own that first night, but I didn't really.) I would definitely return to Mary's if I visit London again.
