Nungwi Guesthouse is clean and great value for cash, cheapest in area. 2 mi walk to beach and has a funky aquarium like theme to the place.
Is located near local cuisine and the grocery store in town. Rooms have private bathroom, nets and fans.
Breakfast is included which is a crepe w/ chocolate, fresh fruit and coffee or tea.
Above all else the staff is extremely laid back and very helpful. Guests I met there ranged from groups of volunteers to middle aged vacationers. Would definitely go back, had a great stay.
