Gung and Martin were quick to respond, helpful with information, and very kind in our correspondence. We stayed for a single night (arrived around 11pm and left the next morning at 6am) so we had a very short stay. We didn't get a chance to meet either of them but did chat with Martin on the phone. The room was as pictured and great for what we needed. The only small issue was the noise from the street below that didn't quiet down until about 4am. We were jet-lagged anyway so it didn't bother us but wanted to put that out there. Overall a good, quick, convenient stay. Would definitely stay there again if passing through Oslo.
