Frank made me feel welcome and more like a friend than just a temporary traveler from the beginning. The location is great, right in the happening section of Kruezkolln. The space is exquisitely curated and the room that i stayed in- the gold room- was just magical. The mattress was incredibly comfortable and the whole space was very clean. The room you get has a key to it which you can keep locked while you are away or while you are there. Frank had great recommendations for food and drink nearby and was more than willing to be helpful if any of his guests had any questions. I will definitely be staying here again next time I get to Berlin!!
