We recently stayed overnight in the Annexe. The hosts were great - they were friendly and helpful.
When we got there, they introduced my nervous girlfriend to the apatments in a really thoughtful way - they took us outside so we entered via the living area, then went into the bedroom, and then ending in the playroom and toy room. So you get to see the vanilla parts before the scary bits. That's much better than the other way around.
They also recommended a good fish & chip shop, so we could get some food to bring back to eat.
The playroom is great - there's a great selection of furniture and anchor points, and a nice selection of toys. Then there's the toy room, which has a massive variety of toys.
We look forward to visiting again.
