We loved our time at Hotel Zinkensdamm! We were able to book private sauna sessions every day free of charge, the breakfast had wonderful vegan options, and there was even a kitchen to cook in. It's situated within a beautiful park, but not far from public transit and nice neighborhoods to walk in. The only drawback was that we got two single beds instead of a queen, but we pushed them together and made it work :) The staff was very kind and it felt like staying in a family-run bed and breakfast. Very quaint and romantic vibe. We loved it!
