Alexander is an amazing host. We came into Berlin a little earlier than expected. He was kind enough to store our luggage until our check in. He also let us check in a little earlier than the mentioned time. He gave us plenty of recommendations and a little history of how it was growing up during the Cold War and the Berlin Wall. Good place is conveniently situated very close to everything. U-Bahn and tram stations are within 5-6 min walk. All in all, it will be really fun staying here. I certainly will if it’s available next time I visit Berlin.
