Phil's place is nice, the room is a good size and there's a desk, and Phil was great. The only downside is that there's not much ventilation -- just one small window that cracks open -- and when I was there, London was mid-heatwave. Since the room is on the 7th floor it holds heat, and it was HOT and sweaty. It's likely a non-issue 95% of the year in London, but as you're planning your trip it may be something to keep in mind.
