Inconsistent--your stay will be great or awful.
We stayed at the Sheraton and the facilities are nice. There's a pool, and our room was spacious and decorated well. However, the staff is less than welcoming. We tried to go to eat at the restaurant and we were told they didn't have enough servers to wait on us (it was a Friday night, and the dining room was half full). Additionally, there was gum in the carpet of our room, which I stepped in, and the shower head was broken off. When we informed the front desk at checkout, we didn't so much as a "sorry for your inconvenience." It's a decent hotel, but can be run down in places, so if you stay here, be vigilant because the staff will do nothing to take care of you.
The location is nice, near the convention center, the lake, and only two miles from downtown.
