Berlin is the best city in the world. My favorite one as I was born here and lived here basically my whole life (except for the months and years I was travelling abroad). Even if I am going to travel, I know that in the end, I will always come back because Berlin – that’s my home.
I love Berlin in summer time because the city is so vibrant, alive and colorful during those summer months from June to September. There are always so many events that you don’t know where to go first. ^^ However, Berlin is always worth a visit also in winter. I will write a post about a winter itinerary and what to do on rainy days later this year.
As you have so many great activities in Berlin, there are often some great deals to find on https://www.groupon.de/ where you can save a couple of euros.
