Shaun's place is in a great location. His room is very large, warm and the abundance of natural light made me feel immediately at home. I was greeted by Shaun's room-mate Jon; a very nice person. My stay was great - I definitely recommend - especially if a central location is important for you.
BONUS: if you catch the express train from Heathrow to Paddington, a cab to Shaun's takes less than 10min.
