June to August in Europe is known as High Season (which means you can expect wonderful summer weather but the downside is quite a few crowds). Any destination in Europe will be a great destination during high season.
If you really put your mind to it, and constantly expose yourself to a language then you may find that you can speak it with relative ease within about 6 months, although as mentioned before, you would really need to be living in a country that speaks that language in order to get to this stage.
Learning to talk is a slow process, and it can take a long time to establish a large enough vocabulary for meaningful conversations. Most children say their first words between 11 and 14 months of age. Popular first words include âmama' and âdada', but could be any word she has heard often enough. By 16 months, girls can say an average of 50 words, and boys have a vocabulary of around 30.
