When we posted pictures of the Windsor online, friends thought that we'd travelled to England. To me, the hotel reminded me of India's hill stations.
Overall, we loved the old colonial style of the hotel and its creaking wooden floors and ancient plumbing. While I was working, the missus stayed back at the hotel and enjoyed being able to step outside rather than being cooped up had we been at a city hotel.
The staff were, without exception, friendly and gracious and its restaurants offer an excellent menu of dishes that, judging from the time it to get the food to our table, was cooked from scratch. The only flaw I would point to was the fact that some of the waiting staff, on occasion, weren't very attentive but that's something I can live with.
The Windsor is pricey but sophisticated and, in my opinion, a lot nicer than some of the 'resorts' in the area. Its only real drawback is the fact that its far from most things including the airport, tourists sites (like the giraffe centre and the Karen Blixen museum) and downtown Nairobi and the city's traffic snarls don't make it easy to get into town.
