Is the Onsea House & Machweo Retreat for Me?

ONSEA HOUSE was founded in 2006 as a small but luxurious boutique hotel. From the beginning this establishment strived to bring greater comfort and better food than any other guesthouse or restaurant, with more personalized service than in a hotel and more privacy than a lodge resort.

MACHWEO WELLNESS RETREAT & FINE DINING was opened next to Onsea House in 2011. Machweo brings an even more luxurious and tranquil environment while maintaining the same personal approach.
All 9 new rooms offer top class amenities and a private balcony and have amazing views on sunset (‘machweo’ in Swahili) and Mount Meru.

Enjoy an amazing meal in our critically acclaimed restaurant by our star chef Axel and his team. Mixing local influences with classic French cuisine and only working with the best and freshest products, every bite and every sip will be an experience for your senses.

Machweo can be your home base for a safari or Kilimanjaro climb with beach holiday extension on Zanzibar, while supporting the iThemba Foundation Baraa Primary School project and other responsible tourism initiatives.

We believe Machweo to be the hidden gem you have been looking for: a refuge for those who enjoy the finer things in life.
