Our particular room (303) needed a new shower head - it was crusted a little with mineral, and was stingy. There was plenty of hot water, however, and the shower was spacious and tiled.
We have stayed at the Riverside Suites twice now, and the location is perfect for the San Antonio River Walk. Rooms have all the amenities of a condo, the beds are very comfortable and the temperature in the rooms is also very good. It was a rehabbed building and still retains the interest of the original building. If you're lucky with your choice of room, you'll look down directly on the river and the restaurants below. The entrance is on the back side, which is an alley, so be prepared for that - registration is on the second floor.
We love the restaurants and the opportunity to walk further up and down the river - there are microbreweries located both north and south of the main loop - and a water taxi to pick you up and deliver you if you don't want to walk.
