Kristian's home has a good location between two subway trains. Short walk.
Good old building and wonderful high ceiling and great wood floor boards! However, we were on the second floor which means we had to climb three floors with all our luggage. Preferred lower floors for our age. Home was generally stylish.
Generally, the size of the home is great. The toilet is small but adequate. Some changes to the height of the shower height and sink will help Asians like us. May want to work on the heated water for bath as the temperature is not consistent and keeps changing from hot to cold water and back to hot over the course of one shower. I'm sure that can be corrected with feedback given to the host.
We enjoyed the home and Berlin was a good experience because we had a warm and big home to go back to.
