Boian and Olga are great hosts and their place is beautiful, modern, brand new, well equipped, quiet, at a great location walkable to lots of great sites and locations in Berlin. There were nice little touches, like a stocked fridge cupboards free to be used. Communication as well ands check-in and out was quick and uncomplicated. For the price of a room at a local 5 Star hotel, here you get a while 5-star apartment with more space and flexibility. I can hardly think of a better place to stay in Berlin.
