We are happy to have recieved you as a guest. As far as noise goes, as we have previously stated, only a few apartments are near the road(those in Panarea and Vulcano) and not the entire residence. Local government is working to put speed bumps on this road as we speak. We are also in the process of having sound proof panels put in the apartments that are positioned near the road. It is strange what you say about the sea because there aren't any industries near our residence. Often after rain and bad weather the water looks a little dark which may be what you are referring to but this happens due to rain water coming down from the mountains. This is the beauty of our beach, being in an open bay!
Anyways, thank you for reporting this to us as every criticism for us is a chance to improve and keep giving our best to our guests so that they can have an unforgettable stay!
