Sigrun was a great host, very friendly, and allowed us to have a comfortable space. Location is good, about 15-20 minute walk to downtown Oslo. Buses are very close by, as well as a grocery store. There's also a great hot dog stand near the park down the street, although it's a little hidden, everyone should try it (called Syverkiosken), it's not inexpensive (especially compared to everything else) and one of the best things we tried while there (try the polse med lompe topped with mashed potatoes).
Thanks again for being a great host Sigrun.
