I gave my wife a gift certificate for The Haven and she had nothing but good words to report.
The staff was very friendly knowledgable, and more importantly, made her forget the stresses of the day as she relaxed for an hourlong massage.
The prices are reasonable (for Westchester):
Spa Manicure $ 15
Spa Manicure w/ hand treatment $ 27
Toe Polish Change $ 20
Basic Pedicure/no polish $ 28
Full Hour Massage $ 80
and it wasn't difficult to get an appointment.
She can't wait to go again.
They also have a comprehensive website at: http://www.havenofbriarcliff.com
