TK was a wonderful host! He sent over very detailed instructions prior to arrival, and was there to greet us as well. He also spent the time to give us sightseeing guidance, which was much appreciated. The apt was very central - close to the Grønlund stop. The full bed in the bedroom and the pull out bed were both very comfortable, and the heated floors in the bathroom were great. TK also allowed us to leave our bags in the apt after our check out time, which was awesome. I would highly recommend staying at his place when in Oslo!
