I had a very nice stay at Denyse's! The location is as perfect as advertised - the surroundings are REALLY gorgeous - and the room was very cozy and comfortable. All the amenities worked perfectly and made they stay really easy with nothing to worry about.
Denyse herself and her husband Rob are very kind and friendly people and it was fun and interesting to talk to them. Rob even was kind enough to give me a tour of the city and take me to the airport at the end of my stay, thank you, Rob! :-)
I can definitely recommend staying there if you plan a long(er) stay in Christchurch!
