Hard to know where to begin, really. My personal experience here was an outstanding one, in every respect. The room was as good as it gets, high ceilinged space with a substantial patio overlooking a glorious view. Well and thoughtfully appointed, the room reflected a serious consideration of the guest's desires - more than just requirements.
The food was even better, again all delivered in cosy surroundings with a very "English manor" feel. The little touches were something to behold: excellent cutlery imported from discreetly exclusive British and other European manufacturers. The quality of the food, largely sourced from local farming communities, felt like real organically produced tasteful produce. And sitting outdoors for lunch under an old African tree and in a utterly bucolic setting with wandering dairy cows nearby and horses (which the manor keeps at it stables for equestrian guests), is nothing to be sneezed at.
Most of all, it is th calm and serene atmosphere at the manor that gets you. Not too far off the beaten track to be a daunting trip to get there, it is still sufficiently isolated to be cut off from the madding crowd, as it were. And there are plenty of grounds to wander about in.
It's not a cheap place to stay at, but there is absolutely no reason why it should be. Value for money, however? I doubt you can find many (or any) better options in Kenya.
