Although the price seems reasonable, Austin's is not good value. It is more of a backpacker's hostel than any sort of a guest house.
It is conveniently located across the river from the downtown, but there is no parking in the area except for permitted residents of the neighbourhood. The nearest paid parking is at the Sophia Gardens bus depot about 500 m away. Cost is ~ 25L per day.
There are very few restaurants or other services in the immediate area (but would recommend the cafe across the river from the Sophia Garden car park for breakfast). But downtown is about a 10-15 minute walk.
The shower doors on our unit were about to fall off and were difficult to close. Our bathroom sink's drain was plugged however there was a shared washroom for some other rooms a floor down. People coming and going can be rather noisy.
There was a kettle in our room that appeared to not work until we discovered that the breaker for it was turned off.
Carpet was dirty--almost to the level of "ikky".
Stayed here for Oasis opening night so it was much more expensive than usual - wasn't everything! Super close to the stadium. Very clean. Didn't get the pre-arrival email but called the emergency line at the front door and was given the codes - really nice chap on customer service who was really helpful. Was expecting a two room apartment so he immediately sent someone over to make up the double sofa bed in the lounge. Has everything you need. Would use again if going to Principality Stadium.
The staff and especially Kenan were always helpful and very friendly on the phone. The rooms are clean but the partitions between rooms as so thin that in the rooms with shared bathrooms, in one of the accommodations, everything that happens in the next room can be heard.
