My boyfriend and I will be living in Bonn for a month ( May 9th until June 10th). We are both Brazilians, but currently living in Australia as I am doing my PhD in virology here. As part of my project, I will study at UniBonn (ukb - Venusberg) for a few months, and he is going to visit me for that period. We don't speak German, but we can speak English, Portuguese and some Spanish tho :D
I will be working during the week and he will be walking around and getting to know the city and the nearby towns, on weekends we plan to travel a bit.
We are a very chilled couple, we like to go out for dinner, watch movies and go to the gym.
