Margaret is a wonderful host. She cooked dinner for us when I suggested meeting up for dinner. Even though the train was running late, and she had to wait for me, it was done with much grace and attention, complimented by sparkling conversation. :)
The place is easy to find, about 5-8 mins walk to Courtenay Place in Wellington CBD area. The no. 2 bus is also a block and a half away, which is available for going to the CBD, Zealandia or Miramar area. It is also close to the Mt Victoria walkway where it will be a 35min walk to the lookout point.
If you don't mind a bit of exercise, I walked from the Miramar shops back to her place in about 1.5hrs, passing by the Wellington/Hollywood sign, the waterfront and the Mt Victoria walkway. It's a different way to see Wellington. :)
