We had an extended stay in Melbourne, and Karen's place was the perfect "home away from home" for us. The array of shops in Rosanna met many of our basic needs, and the short walk to the train and bus stops made getting anywhere easy. The "apartment" was clean, bright, nicely equipped and comfortable. And Karen was very responsive to the couple of small "extras" we asked about. (A burned out light bulb and some other small thing we don't even remember.)
Karen hit the perfect balance of "professional" and "friendly". She, and the rest of her family, became quite dear to us, and it was always good to know they were right upstairs. (In the morning that was sometimes signaled by kids feet on the floor above us - but we liked the kids, and it was a happy sound!)
We're hoping to return to OZ, and can't imagine a better place to lay our heads than at Karen's place.
