The Luna Rio is a nice newer (renovated?) cabin in a beautiful setting, not exactly riverside but only maybe a few hundred yards down a nice path to the Blanco River. My spouse & I only stayed for two nights & spent a lot of that time checking out the Wimberly area, but I would have liked to have more time for relaxing in the screened-in porch and hot tub. Directions for the hot tub controls would be helpful, but it seemed very clean & the water temp was great. There is another, larger house on the property, but there were enough trees & bushes and distance between the two buildings to still afford a decent amount of privacy.
We only reheated some food and made sandwiches while staying there, but the kitchen seemed nicely stocked and everything was very clean. We really appreciated the ice maker in the freezer!
The living room area had plenty of seating & lots of windows to enjoy the views (we saw hummingbirds, cardinals, turkey, lots of deer and a grey fox). Adding blinds would be nice, since you'd have to move a lot of furniture if you wanted to close the curtains at night.
In the bedroom, the only closet was locked and there was nowhere to put bags/suitcases except the floor. A luggage rack or two would be very helpful there. The bed was clean and comfortable, and the room had a wall of windows and a door directly to the screened-in porch, which was very nice.
The one bathroom was the only real negative. While it was clean and had plenty of towels, the toilet was crammed in behind the door, it needed more towel racks or hooks, and the shower curtains rigged up around the tub to make it a shower were really inconvenient - there was nowhere to set your shower stuff, you couldn't bend over without sticking to the curtains, and my taller-than-average husband had difficulty getting under the shower head. Minor inconveniences in the grand scheme of things, but inconvenient nonetheless.
Overall, we enjoyed our stay and thought it was a good value.
