There are so much depends on your budget, from high end to budget. I think the Lion hill lodge would be the best option as they have 4-star hotel facilities and big rooms.
We flew to
Nairobi and visited the
Nakuru recently. Spent 2 nights in this hotel and it was very comfortable with superior amenities, so better try this or have a look on
Nakuru hotels page to get further information.
Nakuru is a beautiful place and having Lake Nakuru and Lake Nakuru national park. As like
Nairobi national park this Lake Nakuru national park has big wildlife area and it's only two hours drive from Nairobi city, so don't miss this:)
