The space is bigger than I'd expected, with 4 separate rooms: bedroom, small office, kitchen/dining, bathroom. Would comfortably fit 3: a couple plus one other. The main bed's very comfy, and there's plenty of bath linen.
Being a loft, it's light and airy. The stairs are well designed and easy to use.
I was in Palmerston North for a conference. Barbara & Alan's place is well located within a few kms of downtown (easy bike ride or drive), and is very close to a wonderful riverside walking/bike path.
