I regret the fact that you happened to be at a time that there was a water crisis in the area. When having vacation with water problems it gives the holiday experience a ''bitter'' taste.This is by no means a constant thing but it can happen seldomly. However, I have gone to every possible extent to resolve this. I have installed 3 water reservoirs with a total of more than 1,5 tone of water (!) for such occasions, where my neighbors have installed just 1 water reservoirs. I did not hide at the very beginning the fact that there may be a possibility that you will face such problems and gave you oral instructions (as well as written ones) on how deal with it. When it comes to ants, this is not a regular problem. When I visited the house after you have left, there was no sign of ants whatsoever. The best solution to avoid ant is to not to leave food exposed, especially sugar and sweet substances. As for the umbrella and the knob, as I told you I had already bought the spare parts and I was around in the area for the weekend but we did not succeed to meet. Anyway, again I regret the fact that you had problems, some of which however where beyond my power to control. Take care and I hope you have very pleasant holidays in the future. Regards, Antonis.
