Could not recommend for business. The free wifi is miserly so you have to buy more - it is not expensive, but the inconvenience and bad vibe surely cannot be worth the charge for Royal Swazi. Plus, there were several times when the internet was 'out' anyway. Room was very large but dated. I had a big balcony but could not use it because it was close to some noisy hotel plant - kitchen air conditioning or something. There was nowhere suitable to meet for business. Lounge area too dimly lit, and often noisy - only suitable tables to work at were outside, where there were mosquitoes, or it was raining, or where, post rain, a gust of wind would deposit an umbrella-load of water on you. The gym was hard to find and a long way from my room, and you had to pay to use it.
Little things were wrong - no globe in a lamp, an empty salt cellar (not even plugged at the base) with room service, an inedible meal. I was on crutches, yet they put me in an upstairs room and there is no lift.
Breakfast buffet was pretty good, and service in general very nice but I would not go back and cannot recommend this hotel.
