We never met Gisella. But Jens received us at apartment building. The communication with the hosts was very prompt. So, check-in was a breeze. Also, Jens happily showed us the whole apartment, & how the washing machine & kitchen equipments work. He also told us about the neighborhood & nearby areas. Location of apartment is good because of good metro connectivity. Metro stop is 5-7 minutes walk from home. Big grocery store EDEKA is just prior to metro station. Jens told us, its one of the few supermarkets in Berlin which remains open 24 hours. So, we could buy groceries, milk etc on our way home late at night. (On Sundays, everthing is closed in Berlin). Apartment building is in a clean, quiet & safe neighbourhood. Apartment is a basic one room studio with big enough bathroom & small attached kitchen. Its a big enough room with 3 proper single beds, 1 small double-bed, one 4-seater dining table, cupboards. KItchen had all the necessary equipments & utensils to prepare daily meals for 4 of us. Small refrigerator (with no freezer), 2 stove induction cooktop, toaster (no microwave), coffe machine, pots & pans etc. Many bath towels, shower gel, shampoo, iron, ironing board, cloth hanger (for drying washed clothes), fast wifi, a revolving table fan & 2 sets of keys provided. WE had a nice comfortable stay. Since there were no host's personal items in the house, we could open all our luggage in it. So, it never felt crowded. We will stay here again & recommend this studio to everyone.
