I had my baby in the home from home at Tommy's recently. Whilst it was bliss in the very calm water pool, they did close the unit the next day due to short staffing, which meant that had my little one been one day later, I would have been labouring in the corridor of the maternity unit or something similarly awful. The home from home is fantasic, but it seems to be more luck than design as to whether you actually end up having your baby there. BTW I used Addison Lee taxis to get there, which I would recommend as the driver was very calm and thoughtful (taking the speed bumps slowly etc) considering I was in full blown labour. Good luck!
