Jan's place is exceptional. At stone's throw away from Alexander Platz and many of the amenities specially for first time visitors, several train and underground stations within 5-2-10 mins walk, it really made this apartment tick all the boxes we were looking for on our visit, in addition of keeping the room spotted clean. Although unfortunately we did not have a chance to see Jan other than on the first day, his flatmate also kindly offered to assist in any questions we had, and also took the time to stay chatting with us on one of the evenings. As an often user of Airbnb, this is a strong recommend
