This is a great place to stay, Maria is very friendly (but also not too intrusive) and the photos don't do it justice! It is a very large room, plus your own entrance and separate private bathroom and extra storage/room with a fridge and tea/ coffee facilities. It is very well partitioned off the main house so it is more like a guest suite than a private room.
The bus stop is just around the corner, and Maria has a GO card so you just need to top it up as you go to save heaps on buses in Queenstown.
It is a very quiet suburb, only a few minutes drive (or bus) to 5 mile shopping centre with a supermarket and food options if you don't want to go all the way into town.
We would definitely recommend Maria's place, and will be looking for it first if we're ever back in Queenstown!
