The ACK Guesthouse is a safe and sensible place to stay in Nairobi. You don't need to stay in a fancy, overpriced hotel. ACK is a solid choice. It's not fancy, but the rooms are nice and comfortable, the breakfast is fine, service is good, and the location is excellent. It's located close to some of the very expensive hotels on "the safest street in Nairobi", according to several of my taxi drivers. The property is guarded and it's a short walk down the hill to the main area of Nairobi. The breakfast is a pretty good spread and was included in my rate. I had lunch and dinner there several times and although the food was a bit bland, there were plenty of choices and the price was reasonable.
