Kristina's place is very conveniently located -- about 30-45 minutes from any major spot in downtown Berlin and 25 minutes away from the central bus station (ZOB). Its about a 6 minute walk from the subway and a 4 minute walk buses that connect you to the S in a quiet and very safe location.
The home itself is a beautiful little space (very modern and chic) with the nicest touches (fresh flowers, coffee, great selection of snacks, and toiletries). We were fortunate Kristina's place had an opening during our time in Berlin. Upon return, we will definitely return again.
