Totally recommend Barish's place! It's nice a cozy, perfect for singles or couples choosing to visit Oslo. Building and premises are extremely safe and secure, close to a rent a bike station, providing easy access to central Oslo. There are a few restaurants and convenience stores around, some open 24/7, again a major plus.
Barish is an amazing host, friendly, open and communicative. He keeps the place tidy and clean, always with a "feel right at home" touch.
