Marek is a great host. He was very responsive and accommodating. Check-in was mostly painless - key pick-up was at a store a block away and was open still at night when I picked up the keys near 11pm. The apartment is wonderfully decorated, large, and well-equipped although a bit chilly at times. The apartment is about a 10 minute walk away from a main area in Friedrichshain with lots of restaurants, bars, cafes, and some parks. I had a great time!
