No Sleep
The Radisson Austin is in a great downtown location on the lake. Although efforts have been made to upgrade and improve this facility, they haven't been completely successful.
Check-in was easy and efficient. The room was large, but the decor was a mix of fabrics and colors that didn't quite match. Sleep number beds are a nice touch, but they didn't help our sleep, because of the poor soundproofing and noise from other guests at 3 am.
We awoke at 3 in the morning to a loud group of young people coming home after a night on the town. Unfortunately, some or all of these people were in the room across the hall from us. We hoped they would quiet down and go to sleep. After almost 30 minutes we called the front desk. The woman working was very apologetic and immediately responded to our complaint by going (or sending somebody) to the room. The noise stopped for a short time, but began again. To make a long story short, the hotel employees weren't able to maintain quiet until sometime after 5 am. 
I appreciated the efforts made by the hotel staff to respond to my complaints. They tried to control the people. Unfortunately there is nothing they could have done to control the lack of soundproofing. 
We checked out the next morning (two days earlier than planned) and the clerk asked us if everything was ok. When I explained that it wasn't and why it wasn't, the response was nothing more than a two word, "I'm sorry." I don't know what I expected in response to this complaint, but I know it was more than what I received. 
Despite the great location, I cannot recommend this hotel.
