Feedback on nurseries (West Hampstead)

[quino]

I'd appreciate any comments on any of the following nurseries: Asquith, Active Learning, Acol and Chaston (Palmerston Road). We are currently living abroad and will be moving to London in the summer. We've been able to briefly visit the nurseries, however, we don't have any word-of-mouth info. Could anyone share any recent experience with these nurseries?
Also, any other recommendations?
Thank you!
