The best way to describe this villa is a home. It was immaculately finished with all of the homely touches you would expect e.g. pictures/paintings, deep pile rugs, etc. with a private rear garden and its own access to the beach. It also included all of the necessities such as fridge/freezer, microwave, dishwasher and washing machine with complementary water and fruit provided. The beds, linen and towels were all perfect. As it's a new villa there were some minor issues, however this was addressed immediately. As luck would have it the owners were living nearby. They were a pleasure and very helpful during our stay.
The area is relatively new so at the time of our stay there were no real shops to speak of. We would recommend getting all of your food, etc. in Salalah, e.g. LULU or Carrefour as the shop near the villa (10-15 minute walk) is over-priced and very limited in stock. The Island Bar/Restaurant in the Marina area (10-15 minute walk) is also worth a visit and a nice place to chill out in the evening with a nice cooling sea breeze on the decking.
The only real downside was that the staff of the Rotana Hotel were not aware of the villa and the benefits of the Rotana discount card, thus made using some of the facilities in the hotel frustrating at times.
All-in-all our experience, privacy and freedom that the villa provided was just what we needed travelling with 2 adults and 3 girls under 7. It would also probably accommodate 2 smaller families comfortably.
