As this area has become more well known, your range of lodging options has increased also.
When we first went to Placencia, we rented a treetop bungalow across from Kitty's Place.
We went a right after a major hurricane hit and there were no tops left on the trees; we wanted to support them so we went anyway. Understandably there weren't alot of tourists there then but I'm glad we went. The business was needed.
The new owners have renovated the resort (some work is still ongoing, so be sure to check). I haven't seen all the renovations so I can't comment on these accommodations now.
I will note that this resort is a little out of town. You can walk to town or take a short bike ride though so it's not too bad. It has a nice beach and is a good place to get away from it all.
The second time we stayed in Placenia we stayed in town at Cozy Corner ($52/night).
It has a nice location on the beach and is close to everything (of course, Placencia isn't that big so nothing is far away). This hotel, while nice, wasn't luxurious by any means but we enjoyed our stay. I wouldn't hesitate to stay here when we return to Belize.
These are the two Placencia hotels we are most familiar with. Of course, you will have quite a few options for your stay. Which accommodation you choose is a matter of personal preference. I'm sure you will be able to find something to your liking.
Two of the top rated hotels in Placencia are Laru Beya Resort Villas and Singing Sands. Although I haven't stayed there, they look wonderful and I will have to check them out on our next trip to Placencia.
