This hotel is the former Stensby Hospital and is in the process of being converted into a hotel/conference center. While initially taken aback by the location and condition, I found the building, setting, and theme to be extremely interesting.
I believe the hotel opened the day before we arrived, so some things were still being organized such as signage, snack bar, Wi-Fi routing, breakfast service, etc. There are currently 80 guest rooms that were formerly patient rooms and everything still has the feel of a hospital, with medical signage, call buttons, and the architectural design of an institutional building. There are new beds as pictured in the photographs. There are numerous lounges (former waiting rooms) throughout the facility, and all of the bathrooms are off the hallways, separate from the rooms. The staff was friendly and everything inside was clean.
The hotel is about 1/2 hour from OSL airport and 1 hour from downtown Oslo. The hotel is close to the highway but in a rural setting. The location is very close to Lake Mjosa, various 1994 Olympic sites, and many beautiful small towns, churches and historic sites. There is a cross-country ski center right behind the hotel.
This hotel has just recently opened and some areas are still being developed. The grounds are large and contain several buildings in various states of renovation. While not for everyone, I found my stay enjoyable and definitely one of the more interesting travel experiences I've had.
