Onsea House & Machweo Retreat




$ 183 (Pps)


Onsea House offers guests a true luxury guesthouse experience with high standards of food and comfort, just minutes from Arusha. Managed by its Belgian founder-manager, it is located just outside Arusha, the start of most safaris in Tanzania. It is very tiny and personal in its hospitality, (only five rooms in the original Onsea). Itfeels more like a European-style restaurant-inn. Machweo Wellness Retreat opened next to Onsea House a few years ago. Machweo brings a more luxurious environment whilst maintaining the same personal service with nine rooms all with private balcony overlooking the magnificent sunset.

Accommodation and facilities

All 14 rooms have views overlooking the countryside and the sunset, air-conditioning, seating areas and complimentary WiFi. The popularity of the in-house restaurant is perhaps unsurprising as the host is a trained chef. Meals can be enjoyed in the dining room but are generally served on the expansive veranda. In the gardens there are places to lounge or relax and a good size swimming pool. Further entertainment can be enjoyed in the private guest bar lounge, including the rare opportunity on safari to play pool. Relax in the wellness centre where you can enjoy a massage or take a sauna or Hammam.

Perched on the hill, overlooking Arusha, the Monduli Mountains and Mount Meru, you can also book the outdoor 'Hippo Pool' Jacuzzi under the African makuti roof of the banda. Others adore the morning gym, yoga or simply reading a book on the Zanzibar-style day bed.

Onsea House is about 45 minutes by road from Kilimanjaro Airport, 10 minutes from Arusha town and 30 minutes or so from Arusha Airport.
