The Keystone Motel is a casual, no-frills option that offers basic rooms and suites with kitchenettes, along with an outdoor pool. The motel's location on Gulf Way Street in St. Pete Beach City is a major plus, with plenty of nearby restaurants and shops within walking distance. Many guests praise the friendly service and comfortable rooms, although some mention issues with frozen toilets, evaporated pool water, and square-shaped pizzas from a nearby diner. The motel's unique charm and relaxed atmosphere make it a great choice for those looking for a laid-back beach vacation. One issue that stands out is the recurring problem of frozen toilets and evaporated pool water, which suggests that the motel may need to improve its maintenance and upkeep.
