Onsea House & Machweo Retreat

Arushas best kept secret Onsea House & Machweo Retreat

Welcome to Arusha’s best-kept secret, the Onsea House and Machweo Retreat boutique hotels now adjoined to provide stylish hotel accommodation for those who need a pampering base from which to explore the northern Tanzania safari circuit. 

Check into this small, stylish and well-furnished boutique hotel in Arusha, offering luxury accommodation for tourists en route to the renowned Serengeti, underrated Tarangire, mind-blowing Ngorongoro Crater, majestic Kilimanjaro National Park or flamingo-covered Lake Manyara. 

Choose Onsea House as a great starting point for safari package tours to the highest mountain in Africa, or to view the annual Great Migration in a town surrounded by coffee plantations, lush forests and the beautiful volcano lake of Duluti.  The name says it all – Onsea House was a home that converted into a cute bed and breakfast with a personalised service ranking far above any fancy hotel twice the size in Arusha. 

Five years later, Machweo Wellness Retreat and Fine Dining opened next door, also as a boutique hotel, and added something even more lavish and special to something already loved by travellers to Arusha. This added 9 more deluxe suites to the four plush en suite rooms at Onsea House that already featured aircon, private balconies and quality décor fit for royalty. Now, the wellness retreat added more space for more visitors who had something special to look forward to in terms of a unique retreat offering world-class spa facilities including a steam room, sauna and swimming pool plus things like yoga, meditation and massages.

The fine dining part of Machweo (meaning sunset in Swahili) is nouvelle cuisine created by highly trained chefs who excel in French fare with an African touch, a funky feminine/masculine food preparation for all guests from around the globe. So, from a simple homely quality boutique hotel called Onsea House, we now have a destination offering intimate dining, spa treatments, a swimming pool and much more. 

Make Onsea House & Machweo Retreat your base for a trip to the northern safari circuit in Tanzania and return in between safaris for a massage, a sauna and a few nights in solitude in luxury suites. Wining and dining in Arusha takes on new meaning at this excellent restaurant. The hotel supports the iThemba Foundation Baraa Primary School project and other responsible tourism initiatives.  



Find the intimate Onsea House conveniently located on the outskirts of Arusha to provide the perfect base from which to explore Tanzania’s northern safari circuit. Perched on a hillock, this stunning boutique hotel lends spectacular views across the Monduli Mountains to Mount Meru and beyond.
