Steinar's place is a nice studio flat, clean, with everything that one might need! The area is very nice, a short tram ride from the railway station, and a 15 minutes walk from Majorstuen. Steinar's is a great host, I haven't met him personally, but he replied to all my questions very politely, quickly, clearly. Everything is well organised and working properly. I'll definitely try to book again this studio the next time I'll visit Oslo!
