I'm really sorry that your experience is so, and I understand that at the sight of some harmless local insects can scare you when you do not know them. We are all doing away with them, and those you have seen have come from previous renters who have not taken care to take the necessary steps to not attract them and as your reservation is made at the last minute, the time Prep was too short to be sure everything would be perfect when you arrived. The internet that was not working was due to a technical problem of the device that we could not settle at 20:00 in the evening and which was beyond our control. The air conditioning worked, except that the remote control was down and you could not adjust the temperature exactly the way you wanted it, but the next day the remote was replaced. For the water probably you had forgotten to activate the pumps, yet the buttons are just at the entrance of the apartment as we always explain when the tenants arrive.
