We had a large, clean, comfortable room on the fourth floor. The only minor complaint was intermittent noise coming from the roof, maybe water heater or air conditioning.
We had AC, a refrigerator and flat scree TV which all worked, and a bathroom which didn't leak - much appreciated after just spending 3 months overlanding in West Africa!
Unfortunately Hotel staff were unwilling, or unable, to give us tourist advice - for example we were quoted 100R, then 70R to have a car organized for a day trip to Nizwa. (Transport only, not a tour) Fortunately we met other independent travellers who told us to take a share taxi, which we did, for a total cost of 18R (a saving of about AU$150). Hotel staff did not tell us about this option, nor give us correct advice re where to find the share taxi. Given an official tourist information office does not exist in Muscat, it is important to have impartial information at the hotel level.
Aside from this we had a very pleasant stay and we would recommend the hotel to other travellers.
