Excellent holiday! Location nice and close to transport links, but quiet and relaxing. Villa pictures do not do it justice - it is huge. A slight issue with the electrics partway through was dealt with swiftly, and didn't affect our plans. Plenty of excursions run from close by, and the beach is within easy distance. The nearby Harman Hotel is indeed a good spot to use a pool, and when you're done you can just wander back to the villa in swimsuit and towel if you feel like it, as it is so close (or there are showers at the pool). I'd recommend the Jeep Safari for fun (pick up from Harman Hotel), and for relaxing, a trip on a small boat that doesn't go to the major tourist spots is ideal (from Fethiye itself, but some will be able to arrange local pickup from the Harman Hotel). I wouldn't recommend this area for diving though, but snorkelling is still pretty.
Overall, brilliant, and we are already planning our next visit!
