My boyfriend and I had a great time spending just over a week at Clarence and Margaret's. The house is located away from the crowds w/ a gorgeous view of the ocean. There is a beach you can walk to down the alley from their house, or it's easy to access areas like Rodney Bay or Gros Islet by bus (closest bus stop in either direction is a 2-3 minute walk). If you choose to walk, Rodney Bay is about an hour away, Choc Beach is in the opposite direction and is a 25-30 min walk. The house is very close to the word "Corinth" on Google Maps. Please be aware that if you intend to walk there are no real sidewalks and sometimes you'll be walking very close to the road. This wasn't a problem for us but it may be relevant to some.
Another thing we liked about the apartment itself is all the amenities that were provided including a coffee maker, microwave, stove/oven.. etc. When we arrived, Margaret greeted us and showed us the room where there were fresh fruits and snacks waiting for us. On our first night Clarence drove us to the Rodney Bay area to pick up some groceries, and gave us a short tour of that area. Clarence also drove us to the Gros Islet party on Friday night.
To those it may concern, the wifi is spotty but functional most of the time. The air conditioning unit in the bedroom works great but without the fan being placed by the bedroom door it doesn't really disperse too well into the living area. Again, these were non-issues for us, but may be relevant information to others.
All in all it was an outstanding stay, and if/when we're lucky enough to make it back to St. Lucia, we would definitely stay here again.
