Kate was very helpful and kind before and during the trip. The location is great - close to the tube and buses as well as Angel high street.
If you have kids, it’s very entertaining as there’s toys, a piano and books to browse. My kids were upset they didn’t have time to play with “new” toys.
The place is her home, so bear in mind that there’s things everywhere and you’ll have to bring your own towel, toiletries, etc.
Our only grievances was the thuds (sounded like they were playing basketball) from her upstairs neighbors until midnight and the bright light into the room in the morning (no black outs). However, both of these were minor for us.
