For somewhere near to Lusaka, but slightly away from it, consider staying at Chaminuka, which is a bush lodge about 30 minutes' drive from the airport. It's one of Lusaka's closest properties to the airport, and so is often use for a night before an early flight – or even a day-room if you have a long connection time.
Chaminuka was the private home of one of Lusaka's most affluent citizens; now it's a spacious and stylish lodge. Its walls are adorned with an excellent collection of contemporary Zambian art (and a few hunting trophies). Chaminuka's stunning main lounge is atop a hill, with sliding glass doors giving a 360° view.
Each of Chanminuka's 19 suites has a telephone, air-con and doors opening onto the lawns.
Inside Chaminuka, you'll find several other lounges, including a sunken TV lounge, a dining room, a sauna, a small library and a snooker room. Outside there are two swimming pools, with an adjacent terrace, a tennis court, a sauna and a jacuzzi. Surrounding it all is a private nature reserve stretching 100km², where 4WD game drives, walks, fishing sorties and riding are available.
