Nairobi is a beautiful and vibrant city. If you have the possibility to do a citytrip , you definitely should! Even if you are going on safari in Magical Kenya, take some time for Nairobi : you will not regret it!
There is plenty hotels, but I am a airbnb addict. I love the idea to have a place for my own, to enjoy the city as a local for few days and following my rythm.
