A short drive from Wellington CBD (about 10-15 minutes), Cath's house feels indeed like heaven on a hill. We travelled with young kids but the steps to climb to get to the house didn't feel difficult. And how rewarding when you reach the top of the hill and enjoy absolutely stunning views from the terrace and the living room. The house itself is spacious and joyful, full of toys, music instruments and colorful paintings. Cath was helpful and friendly, as were the neighbors and co-hosts. I'd love to stay there again next time I come to Wellington.
