Nungwi Beach
Z Hotel & Z2 Hotel
An adults-only four-star on Nungwi's west coast, two linked properties sharing a spa, a gym and a grown-up, couples-first feel. Rooms have balconies and air-con, and the sunset side of the peninsula is the draw. Expect about US$294 a night for an 8.7/10 across more than 440 stays.
