I had a very pleasant stay here towards the end of June 2013. I was down in San Diego for a 4 day education training and did not want to commute every day from Orange County.
I paid the premium rate to have a water view room. The first night I was there, I was in a corner room (loved the light from the windows) but didn't have much view of the water (not that it's at the water's edge). When I got back from my training that first day, I asked if it wouldn't be too much trouble if I could get a room that I could actually see the water from. I was moved from the 8th to 12 floor and the view was awesome. I could even see into Petco Field from my bed.
The staff was great, always courteous.
The ONLY downside was the $36/day valet parking fee. If you don't need your car, I would suggest taking the train down.
