We just returned from a week at the Harbour Club. If you have been reading the other reviews, I don't need to repeat the comments about the hosts, Marta & Barry....but just say that I agree whole-heartedly.
They know and understand customer service and genuinely love entertaining and educating their guests about the island. The villas are a wonderful value compared with other hotels and resorts. But I feel I should emphasize that the villas are located down a long, bumpy & dusty road. It doesn't take too long to get anywhere, but that road is always the start and ending to every trip. I would also like to point out that you cannot get to the ocean from the villas...you have to drive (however, it is not far to a beautiful, secluded beach at Turtle Tail).
I have no negatives at all with the actual villas or the hosts, they were both great. But make sure you understand that you will be driving for everything except the marina for scuba diving and perhaps fishing excursions, which is right down the hill. I wasn't sure from the other comments if you could walk to a beach, but now I know that you cannot.
Another thing I think I should point out is that even the pool/BBQ area is very nice, the pool itself is very small....so if that is important to you, take note.
I loved exploring so many things on Provo and North & Middle Caicos with Marta & Barry's advice, which I probably would not have done if I would have stayed at a big resort. But a nice compromise would have been to stay at a resort for the last couple days to have a beach and restaurant right there, along with a bigger pool.
Another tip: we rented a car from Scooter Bob which was super easy, no hassles. But we opted for the cheapest 4WD and it was open on the back half (I saw many of the same type around town from Scooter Bob). That would be fine except for the dirty, dusty roads. We got somewhat cleaned/dressed up for a couple fancy meals and by the time I got there I felt dirty. Also, you couldn't lock it up. So when you reserve, make sure it is a vehicle that allows you to put the windows up!

We recently returned from one week in Providenciales staying at the Harbour Villas and Marina, what a wonderful place. Marta and Barry were fantastic hosts offering us plenty of ideas for things to do and see in and around the island and surrounding islands. The villas themselves were very clean, comfortable and quiet, it was "our home" for seven days. If you are not in to the hotel life, like we aren't, then Harbour Villas and Marina is the best place to stay. Can't say enough about this wonderful hidden gem.

Having decided that Providenciales was the island that we wanted to visit, we then looked for a "nice" villa or apartment to use as a base from where I ( Janet ) could go fly fishing for Bonefish & my husband Keith could relax, read, explore, take photos etc. We wanted somewhere quiet but nice.
What we found was far exceeded our expectations.
The Harbour Club Villas - 6 of them - are owned & run by husband & wife team, Marta & Barry. What we discovered right from my 1st email to them is that they genuinely care about their guests. They bent over backwards to answer queries and helped us in everything. When we arrived they made us feel sooooo welcome. All the time we stayed at the villa they were always on hand if we needed advice on where to fish / eat / explore, but at the same time gave us complete privacy.
The villas are lovely. Spacious, very well equipped and comfortable. Every villa has it's own private patio and view of Flamingo Lake. Perfect for breakfast and relaxing in the evenings. Or there is the great pool and BBQ area. The grounds are fabulous. Very well maintained.
Marta makes the bed, removes the rubbish, puts fresh flowers on the tables, and fills the bathroom with piles of huge, fluffy towels. You very rarely get that amount of attention in UK self catering! Thank you Marta.
Now for the Bonefishing. I fished right outside our villa in falmingo Lake. No luck there, but elsewhere ( ask Marta!!! ) at a deserted beach with miles of flats, with only Keith, an osprey and 3 pelicans for company, I caught my first ever bonefish. Wow. What a buzz! 2 days later I caught number 2.
I am a moderately experianced fly fisher, and last year had a half day with a guide in Grand Cayman. This plus a lot of practise in casting accuracy, I think enabled me to fisf ( wading ) with a certain amount of confidence. Novices should in my humble opinion book guided fishing for at least a few hours. The bonefish are notoriously difficult to spot, let alone catch!
A vehicle of some description is almost a must if you want to make the most of your stay here. The villas are in a quiet part of the island, and although the distances to beaches, supermarket, restaurants etc. are not great, they would be difficult to reach with transport.
If you are looking for a busy, full of nightlife, beach holiday, then don't stay here. If you want peace and quiet in an unspolit locality, then this is the place for you.
Keith and I can't wait to go back.

We picked Harbour Club from the web and we found a gem. Self guided bonefishing for me, and sun and sand for my wife Lynn to enjoy. The villa was perfect for our needs, well appointed and very comfortable with space for us to spread out. Our hosts, Marta and Barry, were - well - just the perfect hosts, organising a hired jeep for us, and getting us to the supermarket to stock up with necessaries for the week. I was able to find bonefish within minutes walk from the villa, even though this was my very first time fishing for them. So fishing before Lynn got up in the morning and in the late afternoon after a day out was easy to achieve, which made for a very happy holiday for the two of us!
