Casa Placencia was easy to find and convenient to get places. Although right on the main road to Placencia Village, it wasn't noisy. There's a grocery store within walking distance that even takes credit cards (the ones we found in other parts of mainland Belize do not).
The 1 bedroom apartment is toward the back and right next to the (very small) pool. The apartment itself is kind of quirky but clean and well-equipped, with lots of storage so we weren't tripping over suitcases or shoes.
Jacki and her staff were super helpful and available to answer questions, make suggestions, and do little things like set up an umbrella over the pool.
Overall, it was a great, non-hotel like place to stay while we explored Placencia as a.place to retire to.
