The earlier reviewer who said that this is a rare find - is 100 percent correct. It is superb. The apartment is just as in the photos.., only larger. It is modern, tastefully decorated, fresh and clean. The kitchen is fully equipped, TV channels galore, and beds are very comfortable. As we (2 adults and 2 primary school aged boys) were there in December it was lovely not to run the aircon but to let the breeze from the sea drift in through the netted windows, combined with the quiet made for restful and tranquil evenings.
The hosts are wonderful - truly kind and warm people. They made us feel very welcome and were only to ready to aid with any queries or provide assistance - yet were not intrusive. We cannot say enough kind words about them - so will leave it that!
The location was great for us. A couple of kilometres up the road are unspoilt and largely empty sandy beaches, bliss. For those who do not want to explore so far there are 2 pools at the modern resort setting (where again there were not too many people at all) . We highly recommend the Bank Bar - the infinity pool which looks out directly along the coast is to die for. Our children were very happy there.
For those that want to venture further there is a boat that runs to Muscat a few days a week. If you ask the boat operator it may return later than the morning programme - as we found.
The drive to Al Sifah is mountainous and windy and takes around 45 mins to drive (if arriving late you may consider taking a taxi or driving in morning) so the boat option is very good (plus scenic and reasonably priced,) if you just want to make a visit to Muscat e.g. to buy groceries (as there are no supermarkets/food stores at Al Sifah beyond a small shop selling a few mainly dry staples).
In sum, we loved staying there and highly recommend it to those who will appreciate and take care of the apartment ahead of our next return!
