Poinciana House could not be more conveniently located, right in the centre of town. The house itself was well provisioned, the outside area in particular was fantastic.
There were a couple of minor maintenance issues (blown bulbs, bins hadn't been emptied) but overall the experience was good.
It does mention in the ad that the house is actually managed by a holiday rental agency, but do be aware that you'll need to log on to their guest portal as well rather than everything being handled through Airbnb. This was not difficult to do, however.
