I stayed at Maya's place for six nights and fortunately got a chance to meet her in person for a day (which seems quite seldom with her hectic schedule :D). She was very helpful, she helped instantly on phone, IM and emails. And also she toke me on tour around Brixton and we even enjoyed an evening at a nearby pub. The place is quite friendly, cozy, clean and has good transportation access to bus and underground.
In short, I would definitely stay there again :)
