When we went down at Easter it was ok. However, when the family (minus me) went down in Whitsun flys and mosquitos were more prominent and apparently gets worse during the summer despite the fumigation attempts by the resort.
So we have decided to invest in a Mosquito Screen for the Patio Doors. We have approached a company called VIP Services; just waiting for him to measure up and quote but he indicated it would be about €180 for just the Patio Doors.
Plus we also had the Utility windows sealed shortly after we completed!
