The place is great! It's a small guesthouse. it can be perfect for a family/friends comprising of 4-5 persons.
Please note, it's a long way from the center of Berlin. At least 45 minutes to travel from this guesthouse to the center.
Rest, its all good, there is a heater equipment, and there are temperature controls for the floors to be heated.
Just in case if you are willing to get this place for the pool, please note due to winter season, the pool will only be usable from May on wards.
The hosts were great, responsive and friendly.
