Mary's South Austin Cottage is one of the most lovely places we have ever stayed. Myself and three others (girlfriend, brother and childhood friend) were in town for 4 nights for a wedding. This was the perfect place for us to stay.
My girlfriend and I took the room with the double bed and my brother and friend took the two single beds. The kitchen was large enough to cook meals and well stocked. The patio was quiet and cheerfully lit for us to enjoy dinner under that Texas sky.
I highly recommend this if you are in Austin. You will not be disappointed.
