This beautiful outdoor swimming pool is an oasis in Milan when the weather gets too hot, I…read morerecommend going there on mornings on weekdays - unless you want to stay all day. It's quiet and cool and has a really nice bar where you can have coffe and snacks. Remember that you must wear a swim cap if you want to swim and you'll also need flip-flops but you can buy both here.
Another great feature is the aperitivo which starts at 6.30 pm and goes on till midnight at weekends.
