Casa Placencia (aka Jacki's place) was a good place for us to stay in Placencia, what really makes great is Jacki's hospitality. Jacki helped us with so many things from renegotiating our taxi fare from the airport, to providing freshly baked muffins, to helping me get my credit card back (I left it in a store). Jacki is a wonderful host. We enjoyed meeting her and took advantage of her local knowledge.
The apartment is comfortable, having a little extra room and a ground floor apartment was important for us as we brought a lot of dive gear with us and the extra space meant that we didn't have to trip over our gear all the time. The bed, while comfortable is quite high off the ground and required a small leap to get into (I'm 5' 3"). The kitchen had everything we needed and we cooked breakfast each morning. We felt very safe and at home there.
We were about 0.5 of a mile from the hub of Placencia and bicycles are provided which made it easy to get around, and it helped that we had torches as at night its quite dark and the road has potholes.
I highly recommend Casa Placencia and hope to stay there again in the not too distant future.
