Two days private safari, worth to recommend
First of all I must say that safari in Tsavo East is unforgettable experience. The views and presence of wild animals was a very special moment in our lives, and we're simply out of words to describe how incredible feeling it was. Karanja and Chris were very nice and they showed us lot of interesting places and animals. We felt secure and well cared for whole trip. We didn't have a luck to see male lion, leopard and rhino (for the last ones Tsavo West is probably better), but that's undersandable risk with wild animals.
We agreed with Chris to change a bit second day of the trip, to have a tour through Mombasa (Tusks, Fort Jesus and Spiece Market).
Reason for 4/5 stars is unexpected change in location of our accomodation as we chose Voi Safari Lodge, but due to overbooking we stayed in Voi Wildlife, and we'd been informed of this fact in front of the second lodge and not earlier. I know, that it's due to lodges management, but comunication could be better. Voi Wildlife wasn't bad, but it was cheaper option in other options so that's why I've been a little disappointed. Tsavo East helped me to get rid of bad feelings though :)
Tips for others: 1) Jeeps seems like a better option not only due to their appearance, but also they allow the guide to join looking out for the animals. 2) Mombasa tour wasn't that special as safari so it's better to use two game drives at second day.
Generally I'd recommend this trip, with minor remark to Chris.
