Owner's Response: Of course, I was unhappy to hear reports of the pool malfunctions. However, the pool man in fact been there the day they arrived and brushed down the pool walls and floor, cleaned the pool and balanced the chemicals. So my report from both the housekeeper and the poolman, is that there was a bit of cloudiness from the brushing, which is normal, but that this was explained to the tenants, and that the pool was otherwise clean and chemical balance was perfect. So not green at all. Someone, and I simply cannot know who, played with the valves for the pool and pump and put it on drain(!) so that it cost me a fortune to replace the lost water. Now, I am in London and coordinating with two poolmen (as I had another come out, as "my" guy only comes once a week) and hear that this someone has opened the drain and been moving the valves, while the pump is running, damaging the filter valves, which needed replacing, another expense. Now I cannot know who was mucking the system up or causing the damage, but my reports from the poolmen and housekeeper are telling me one thing and the guests are telling me another. It was also reported that they used the pool all the time, including their dog, which was in it constantly. As the reports were so disparate and the last I hear was "we would like compensation", yes, I decided not to keep going back and forth with him. Rather than risk an argument, I just decided to assign a bit more weight to the information I was receiving from the poolmen and housekeeper. It is correct that when the parts arrived, they were incorrect, which really irritated me. But again, these things sometimes happen and I have two companies and a great housekeeper spending hours a day getting things done. ...and the pool was refilled immediately and in balance. So to claim that they did not use the pool for 5 days is not in agreement with the information I have from all other sources. What to say? And because the filter was out of the loop, does NOT make the pool unusable, as anyone with a pool knows.
