We stayed here on our first night in New Zealand and fell instantly in love with it's eclectic, homely charm. The house is a classic Dunedin-er with bay windows and has been decorated with the hosts vast collection of bric a brac and collectables.
Our room was at the back of the house and very quiet and warmed by a space heater. We eventually met the host, Joyce, and she was great - very chatty and had good advice on where to get a drink and something to eat locally. Arden Street House comes with a couple of resident cats who frequent the hallway and the lounge (if encouraged) but not the bedrooms. If you are allergic to cats you may need to know this. The breakfast was good with as much DIY french press coffee or tea as you can drink. We enjoyed our stay here and would stay again should we visit Dunedin in the future.
However, a note of warning in regards to finding Arden Street House - Arden Street itself is broken up by a steep set of stairs and many people, us included, were bamboozled by this and knocked on the door of another place called 'Arden House' at the foot of the stairs. This house has a note tacked to the door saying they were not Arden Street House and providing directions to the our destination. Contrary to what others have written here, no long slog up the stairs is necessary, unless you are arriving on foot when this is indeed the quickest way to reach Arden Street House - if you are driving or being driven, you can park directly in front of it and there are no stairs to climb.
