The location is definitely the best part of staying with Gung and Martin and their family. We had early trains out of Oslo and being within 10 minutes of the central station was important to us--walking to and from their place was a breeze. The room was clean and easily accessible, close to the main door. One thing I'd mention is that you're sharing a home with a family so be prepared for that. It wasn't an issue for us, we thought they were great and never had an issue with anything including the shared bathroom (stayed with them two nights on the first and last night of our visit to Norway). And then just also note that you're only getting a room here, there isn't access to the rest of the home (aside from the bathroom across the hall) for lounging etc. But, you should be out exploring the city anyway so this is a great basecamp to come back to for the night. Thanks to Martin and his family for hosting us and for the helpful tips you provided!
