I stayed here with two friends for six weeks when in Saint Lucia for a placement at Victoria Hospital in Castries (medical students).
The apartment itself was well kept and clean, with good furnishings. Maria and Theo are a lovely couple who live above the ground apartments. They bought fresh flowers regularly, which was a nice touch. They also offered the empty apartment next door to one of my friends at a great rate when his fiance came to stayed for a couple of weeks.
The location was good, with a bus running to the town center regulraly from nearby the house. It was also not too far to walk to the beach, or to the local super market.
The only thing we missed on our trip was air-conditioning in the apartment due to the heat at night, although there were fans in all the bedrooms which helped. The apartment was also situated at the top of 'Active Hill', so called for a reason! Good for the calves though and not usually an issue due to the regular bus service.
Overall, a lovely and welcoming place to stay, all of us would highly recommend it.
