My wife and I had a very pleasant stay in No. 8 Mira Mar. It had all the amenities that you would require, with a comfortable bed separate from the lounge area. Although, this unit is the centre one of three, we found it to be quiet, even with other people on either side and being close to a main road, of which we didn't hear any traffic noise.
The unit is close to all the amenities that Albany has to offer, including a visit to the ANZAC Memorial Centre, which is highly recommended. I would suggest allowing an all day visit, as we spent 4 hours going through the centre and had to go back the next morning to see the outer areas.
I would recommend a stay at Lyn's "Mira Mar" and we would not hesitate in staying there again on any other visit to Albany.
