Thanks Johannes to be my guest. I would like to take an advantage and explain about mosquitos complain I read in the recommendation done before. Unfortunately, all Barcelona area is suffering a real invasion of Asian mosquito (tiger). The local government prepare the area before summer time, as well the property usually also does (spray the area with environmentally friendly products and people). Anyway, this last 2018 summer could be annoying due to a lot of rain last days. Regarding, noise coming from planes I would like also to clarify it.
The Barcelona airport is very closed (less than 20Km) and has three airplane tracks. Depending of the wind direction, this could affect and disturb but never during the night. This is a common situation of all the area. In the other hand, you can go walking to the beach. If you really want no noise at all, my recommendation is to rent a property at the mountain, which means almost 30 min to go to the beach by car (paying to park the car in case you will find a place to do it!). In more than 40 recommendations, this situations related airplane noisy has only happen in 2 guest an only in determinant hours due to the wind direction. Hope this clarifies and help my future guest to decide the best for them! Best to all!
