It's my sixth day in Valencia, and I'm being attacked by mosquitoes

This night felt very long because I couldn’t fall asleep again. I heard mosquitoes flying around and even getting bitten. I couldn’t even hide under my blanket because it was too hot, and that moment was really annoying, I just didn’t know what to do. I still have no idea how I can fall asleep or where all the mosquitoes went. I finally fell asleep at 3 AM and woke up at 8 AM, so I only slept 5 hours in total.
