Thank you for bringing this to our attention. We are so sorry about this and apologise for any discomfort you are feeling. While in the UK during the summer, biting insects such as mosquitos can be an issue, especially when windows are left open during the night. We take your proposed reasons for your discomfort very seriously and will immediately put our management plan in place to firstly, identify the problem. And if it is as you have suggested, arrange and implement a swift treatment of the situation. The comfort of our guests remains our first priority, and we apologise again that you did not have a comfortable stay.
