For a mid-range hotel in a smallish town known mostly for its wineries, I was pleasantly surprised. I traveled here for work, and stayed 3 nights. I had a double-queen room to myself in the main building.
The hotel is spotless and welcoming, and clearly has been updated in the last few years. I didn't get to use the outdoor patio, but it was very inviting looking. The lobby and breakfast area were extremely clean and there's a fountain/bottle filler for your fresh drinking water needs just off to the side. All of the staff I encountered were warm and friendly.
My room was also spotless and included a decent size bathroom, a kinda-kitchenette with a mini fridge, microwave and Keurig, a desk, and a chaise lounge chair/reading nook in the corner. There are plenty of lights and outlets for charging things. Lots of pillows and very comfortable bedding and mattresses.
My one small design peeve: the bathroom door blocks the shower/tub when open, you pretty much HAVE to close it to get in, but there's not much anyone can do about that. Water pressure is maybe a little too good, would have been nice to be able to adjust the showerhead. Plenty of hooks and racks and towels were refreshed daily.
I did not use the pool or fitness center, so I can't comment on those, but they are available. The breakfast selection is really good, honestly - fruit, pancakes, a wide variety of baked goods, hot items like omelets, sausage and bacon, yogurt, cereal, juices. It didn't vary much the three mornings I ate there, but it was tasty. Coffee is good too.
In the evening (at least during the week) there's a manager's reception with snacks (popcorn, snack mix etc) and usually 2 wines and 2 beers to choose from. Nice little perk.
The location is not really walkable to anything besides KFC next door, but it's convenient to the highway and downtown Paso Robles, which is a cute area. Parking is plentiful though a little oddly laid out.
I don't know if or when I'll be back in Paso, but if the time comes, I would definitely stay here again.
