Alex's place is lovely, modern house with a great bathroom & shower. Not much to expect from the private room, just a queen size bed and a closet, but that was fine for us(just a small table & chair would have been nice).Kitchen has everything you need, living room is very modern and pretty, terrace is a chilled space where you can hang out.
Regarding location we were a bit disappointed, there's not much around, just a local supermarket, somewhat more expensive than Woolies or Coles and a park, which is fine seeing once but not as the only attraction for a week. If you have a car or are willing to spend a bit for public transport you'll be allright, but even the next Woolies is 25 mins away by bus, which was inconvenient for us since we didn't wanna bother Alex by asking him for a ride, which he would have granted us with no doubt.
Also the airport is rather close, so you have a bit of a noise occasionally, but due to good isolation that's not a huge issue.
Alex is very polite and friendly, gives you everything you need. Sadly, our interests didn't really match, so we just chatted occasionally and did our own thing essentially.
To sum it up: nice house, basic room, unsatisfying location. Still had a good time.
