I was happy and cosy staying here. Although I was alone, the big advantages of this place are FOUR double bedrooms, suitable for 8 people! and a good kitchen, and very central location. It has Netflix, which I don't often get to use. The place is simple but very organised and clean, it almost seems like an old beach shack if that makes any sense. You could have nice evenings playing cards and board games etc here - lots of chairs, couches, space, blankets etc, nice and comfy.
Main disadvantage (only if you have a big group) is the one shower and one separate toilet. Also, it's above a shop with >15 steps so not accessible for people who are frail or have limited mobility.
Communication and check-in were good. There's parking for one car around the back. Nearby are many places to eat and have good coffee, plus a cinema and general shopping. It's extremely close to the airport. Invercargill is cold so be prepared!
