We had a great stay in Sebastian's place. The location is ideal and surrounded by really cool bars and eateries with excellent transport facilities allowing you to get to anywhere in Berlin easily. The minimalist yet functional interiors create an almost gallery-esque feel with large bathrooms and bedrooms giving you a true sense of luxury. The fact that its also off street allows a quiet space to exist. Sebastian (who lives nearby) also proved to be a great host, on hand to answer any questions you may have on Berlin. He's a cool character as well, and knows all the right places and areas having been a veteran of the Berlin creative scene himself. We would definitely recommend this place not just for singles or couples but also to creative agencies looking for a base to establish themselves in Berlin. Definitely a place I'll be coming back to again and again.
