I give Mr Vinny 5 stars because when he came to change my filter with a smile after the wrong one was given to me he was polite and quick. Usually it's a weird feeling as a woman to deal with anyone coming into your home but he made me feel safe and comfortable. One thing I can say is that I have never had any problems with any of the maintenance people they come across friendly and helpful. Always willing to go the extra mile to help you with your issues.
