This was not at the heart of the Riverwalk, but that was okay for us, because it is easier to park on this side, and it is less congested overall.
Also, the price we got via Priceline was fantastic--under $50 a night!
From the hotel you can walk to the Riverwalk area or you cna buy water taxi tickets at teh gift shop. They taxi comes on a fairly regular basis but unfortuately last one is around 9 pm which seems early for a tourist city.
Accommodations were good rooms, a bit smaller than I thought but ample, and the pool on the roof was decent too.
Parking was gratis nearby, as long as you were a guest there.
