I recently stayed at Nicole & Shane's apartment with my Mother. I was in Christchurch for work and my Mum was being tourist. The apartment was perfect! It was in a fabulous location, so great for my Mum to get around to check out the sites, it was very spacious and warm and had everything we needed. It was great for me also as I'd go to bed early and Mum was able to stay up watching TV etc if she wanted and with me having the room at the other end of the apartment, I couldn't hear a thing. In fact in general the place was beautifully quiet, so I slept well. We were there for 3 days and loved it and didn't want to leave. Great also to have car parking... the car stacker took a bit of getting used to and you have to be careful getting in and out (so extra careful if you're wearing heels and careful of your clothes navigating around the chain/cable).
All in all, we would highly recommend Nicole & Shane's apartment and I'll definitely stay there again if I get the opportunity. :-)
