There are a trillion little Hotels in Bayswater. That's where the 1st
KR London Hotel Party took place. It's also where I work.
I wouldn't go out east. Maybe I am biased because I hate it, but I always feel like East London is super not well connected to the rest of London, especially if you want to avoid buses. You have to catch the overground and it is a ****ing mission. Plus, you'll be surrounded by hipsters all day every day.
