This apartment is super. Jan was very easy to contact and quick to reply to any messages. The apartment was warm and cosy. Be careful to make sure all water is drained before getting out of the shower or else you'll have a puddle in the bathroom! We were pre warned by Jans friends who were very welcoming and showed us the the tram stop. About 20mins tram from alexanderplatz but we had a travel card so was fine for us. A lovely stay - thank you Jan!
