Hello Sharon, we are sorry to hear you were not 100% satisfied with your stay at Villa FL003. We have never had complaints of the pool heat not working. This is controlled by a gas heater to the side of the property, not by a pipe into the pool. The management company in Florida are ususally very quick to respond to any issues with maintenance, so I am sure if they were made aware that the sink continued to be a problem, they would have resolved this for you. We will of course pass your comments on to them.
