Gelfo's place is very spacious & conveniently located between Messe Berlin (2-3 stops away) and city center (3-4 stops away). There is a coffee shop right behind the house. On the way to the metro (5-6min away), you can find grocery store, pharmacy, bakery, and restaurants. The house is located on the 5th floor (with no elevator). So for those who come from places where ground floor = 1F, be ready to climb some stairs and exercise! The high ceilings and view will not disappoint.
Most importantly, Gelfo and his wife responded fast to questions and were extremely helpful. They are so kind for sharing their beautiful home. Many thanks to them.
