This place is exactly as advertised. Spent 4 nights in Vienna with my husband and 2 sons (17yrs and 19 yrs). It was a little tight, but we travel on a budget and this place fit our needs. We only spend time at the apartment to sleep- spending the day out and about so "coziness" is not a problem. Beds are comfortable, building is quiet so it was easy to get a good nights sleep.
Metro is super close and super easy to ride. Grocery stores are close, so breakfast was yogurt, bread, and fruit. I would recommend any apartment run by Kemal and his wife.
