Martin's place was perfect for our stay in Berlin. I came traveling with a friend, and the loft style sleeping arrangement was perfect with very comfy beds. The apartment was also much larger than we expected. Everything was clean with cute touches throughout. Christina met us upon arrival and walked us through the space. She was incredibly sweet to loan us a few power adapters once we realized we had forgotten our own. The first morning I texted Martin with a question about the hot water. Three minutes later there was a knock at the door, and he arrived to show me how to adjust the water heater. I was so thankful and impressed with such prompt hospitality. The area was great. There's a bike shop across the street where you can rent bikes for 10 euros a day. The surrounding block has some good resultants and cafes, or head north towards the river and find plenty of cute neighborhood restaurants, bars, and coffee shops. Loved the location. Would definitely recommend to anyone traveling to Berlin.
