It's a pretty basic hotel, but that's all we were looking for. The breakfast was really good! I loved that the riverwalk was right behind the hotel.

We choose this hotel for its location on the river walk and its convenience. Friendly staff and reasonable rates are another reason.

Pool staff were nice. Suggest that check in let people know to bring an ID to the pool if they’d like to get alcoholic drinks. Pool area structures are rusty and look dilapidated.

This property (other than the lobby and breakfast area) is so outdated, it’s embarrassing. The hallways and guest rooms are terrible; carpet gross, walls super dirty, zero upgrades in them. For this being a resort on the river there is a lot of opportunity being missed.
