You are going to have a tough time beating this location IMO.
Really convenient for me or probably any regular Austin traveler as it is a block of Congress & 6th.
Great two level loft with good space and full kitchen.
I screwed up my travel dates when I originally booked and Top Trip accommodated the change I need almost immediately.
(Glad it worked out but would have been my fault)
Great communication and super easy check in/out.
Given the location they do warn you about the noise but I didn't notice at all.
I could see it being a possible issue at a lower level but hey you are staying next to 6th Street.
