Good:
Room accurate to pictures.
Easy check in/out
Good communication
Everything you could possibly need is already supplied
Good hot water
Awesome location to city attractions and tube (zone 1)
Reasonably safe location
Clean
Bad:
4 rooms all Airbnb so up to 8 people at one time making shower/bathroom time busy in the mornings
By the end of the day place can get very messy/dirty due to quantity of people
Matts really annoying as they are curled
