Living in Berlin is really easy and accessible, rent in the student accommodation was very cheap and the rooms were a good size and had their own kitchen and bathroom which was super helpful to have in a student place. Water and power was included in rent and I found it very easy to live on 100 euro a week (monthly rent not included) with grocery shopping being easily available and cheap.
German is not too difficult to pick up and a lot of people in Berlin speak English as well, the adjustment period was daunting at first but I wouldn’t let the language barrier be off putting, it was actually a fun challenge but English was also easy to use if you got stuck. HTW provides a short German course I would also recommend taking up German as a subject while studying at HTW if you can because it’s a great skill to have and well taught. Studying in German was also a difficult but interesting experience, I did not speak any proper German before I left and while HTW was extremely helpful it was also a great incentive to practice more German day to day, but even when I couldn’t understand I was also given information in english which I appreciated greatly. HTW’s fashion design degree and general subject system was slightly different to QUT, I personally found the workload to be not too difficult or time consuming, but challenging enough that I knew I was getting a valuable education experience as well as that extra freedom to engage with Berlin culturally and gain out of uni experience as well.
