This place is a must. I stayed for a month.
1) Location - Its a 20/25 min walk to the CBD. Which I used to walk everyday (most days). However, if its not your thing, there is a bus that is literally 30 seconds from your door and goes every 15 mins. Takes about 8 mins to the CBD and also drops you off outside Perth Train Station.
2) The Place - Lovely bungalow. Spotlessly clean, you get you're own room with aircon (which became my best friend). Great wifi, your own private bathroom. Their house is your house. You have full use of the kitchen, sitting room etc.
3) The Hosts - The guys were lovely. From day one I forgot they were strangers, it was like living with friends. They did everything and anything for me. Well beyond what is expected of a bnb host. Made my time in Perth a lot easier.
