Had the complete, pretty flat for our selfs and loved to stay there for a few days. It's very clean and fully equipped - we'd even do out laundry. The flat is near the octagon (15 minute walk) so it is easy to get to town. Communicating with Kristina was also a pleasure as she always responds quick and answered to our questions.
We'd definitely recommend to stay at Kristina's if you're around Dunedin!
