Nigel's house has excellent views of the bay from what is a unique property: I can't think of any others I've ever seen with their own mini-cable car (great fun!), plus the wooden floor throughout is beautiful. Our room was clean and tastefully decorated, with good-quality linen and towels, and a very effective heater.
While a little dated, the bathroom had a very good shower, and a generous range of breakfast options was left for us in the adjacent kitchen.
Our visit was, unfortunately, fleeting: my girlfriend and I didn't get to speak to Nigel as much as we would have liked, but I got the impression that he would have been very helpful had we needed advice on what to see and do.
Light sleepers should bring ear plugs, as the room overlooks a slow-moving freight train line, a main highway and the Interislander ferry terminal, so it can be a little noisy at times. However, the relative proximity does mean that it's only a 10-minute drive to the ferry terminal if you're heading to the South Island, as we were. An Uber into the city centre from the house costs about $10-12.
Nigel's place has character and I'd recommend staying there to explore Wellington.
