My wife, myself and another couple stayed at The Arches from 2 - 10 March, 2005. We Loved it! First of all, the owners (Cecile and Wally) were great. They were so friendly and went out of their way to help us out (recommendations on where to eat/shop & what sites to see. They let us use their phone to set up dives/bike rentals, they even gave us occasional rides downtown when we needed them)! It was a very relaxing and 'homey' environment.
The townhouses were very large and immaculate (Cecile keeps a clean house!). With four balconies there were plenty of fresh sea breezes and beautiful sunrise/sunsets. They have a great gazeebo and fresh water pool which was the perfect setting for cooking out, watching for "the Green Flash" at sunset, or taking a mid-day nap on the hammock. Each room has a full kitchen, coffee maker, microwave, and blender for frozen cocktails.
The people of Grand Turk were refreshingly friendly and the diving was awesome! (We used Blue Water Divers and they were kicked back, friendly and fun).
When we go back, we will definitely stay with Cecile & Wally at the Arches again!

My wife, our 4 grown children and I (staying at the Osprey Beach Hotel, popularity #1) heard about The Arches (popularity #6), and biked past it at the top of a "hill" on our ride to the lighthouse on the north end of Grand Turk.
This is a brand new place, folks !! If it wasn't important for me to be on the beach, I'd give this place a try. I don't know about cost, food, etc., but I wanted to make sure all readers know it's new. If you don't stay at the Osprey Beach Hotel, like "new" and don't choose to take a chance on other Grand Turk accomodations, this is probably your place.
I read the July 4 review written by the people from St. Louis, and The Arches sounds nice.

We stayed at a place called the Arches. They were very, very, nice. Two bedroom condo (or townhouse) Unbelievably clean. And two full bathrooms; Full BIG kitchen. the whole place is big. Very, very, very big for a condo. (we have friends that own smaller condos than these) The bedrooms which were on the second floor were air conditioned but not the first floor. I thought this might be a problem but they are up on a hill and get a great breeze. (I usually die without air). They have a nice pool. The owners are really great people and went out of their way to get up some help we needed. We saved a lot of money on food by fixing some of our own food. For people who need space and want a VERY nice place, I would highly recommend the arches. (One of my daughters stayed at the island house, which was OK, but in comparison to the island house not as nice)
For people with kids—the owners LIKE kids. ( We have had some places discourage them)
The only downer would be they are not right on the beach and you will need a car-though if you are diving Oasis will pick you up (I think all the dive shops do pick up)
By the way diving was GREAT-much beteer than Provo
