Well located within the Lake Nakuru NP, the Sarova Lion Hill suffers the consequences of being situated relatively near Nairobi, therefore overrun with day visitors and conference groups.
I had emailed the reservation desk and asked for a 'good' room, not knowing what to expect. We were allotted Room #22, next to which is a Suite, the last room. So we probably got one of the best non-Suite rooms, far from the busy main block, The room overlooks the garden and Lake which seems to be only a stones throw away. The ceiling to floor mosquito net is spread out in the evening. The bathroom area is huge, as large as the room, perhaps larger.
The restaurant suddenly turns peaceful as soon as the conference groups head back to their meeting rooms, so it would be useful to time your lunch accordingly. The buffet spread is vast, with a reasonable choice of Kenyan cuisine, which I was keen on sampling.
Staff and services are very good, in spite of the crowds.
Tip: ignore the 'urban' atmosphere, with busy looking folks pacing up and down yelling into their cell phones, and avoid peak times at the restaurant.
My teenage son and I travelled in April. We did not encounter a single mosquito!
