I have stayed at the Fairview twice in the last 9 months and really like the quality of service there. They really aim to create a very pleasant experience for every type of traveler.
I've found nearly all the staff to be very pleasant and helpful. For example, once I was dissatisfied with a meal and didn't eat it. I had no intention of complaining about the meal - I simply sent it back and paid for it. However, when the chef noticed that I didn't eat it he immediately offered to prepare me something new (for free) or give me dessert (for free). It wasn't necessary but a very nice gesture.
I like the large size of the rooms and bathrooms, the functional design, and the overall quality of decorations, etc. in the rooms. The internet in the rooms and the common spaces is pretty good. Their gym is well equipped and maintained. Their lounge (with the fireplaces) are also well-kept and very cozy! The restaurants are fairly decent and I like that they revamped the menu for one of them in during the 9 months that I was away. The quality of the food is average, not exceptional, which is why I can't give 5 stars.
I also like that they have arranged taxi rates with a select group of drivers and posted it in their lobby. (The rates are a bit outdated now.) It's also a huge relief to have the Israeli Embassy next door, which heightens the level of security in the area.
At the end of a busy day, I was actually content to return to the hotel instead of dreading it. That's important since I usually spend at least a week there.
