Onsea House

Onsea House is awarded the best place to stay in Arusha * and recommended by several experts** as boutique hotel and hip hideaway in the Arusha/Kilimanjaro region. Enjoy 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. Onsea House can be your home base for safaris across northern Tanzania.

The original Country Inn consists of 2 cozy and tranquil suites opening onto a large shared terrace. The adjacent self contained Guest Cottage, each room with private wooden balconies, can easily accommodate 6 people. Experience the calm African-Colonial setting, with tastefully decorated rooms with four poster beds, mosquito nets and en-suite bathrooms.

The outdoor Jacuzzi and private floodlit swimming pool with lawn bar are the perfect place to prepare or recover in style from your safari or mountain climbing adventure.

The new Machweo Wellness Retreat & Fine Dining offers the finest spa & wellness facilities including steam bath, sauna and additional separate swimming pool. The beautiful main building houses also 3 double honeymoon suites with luxury bathroom with both bathtub and walk in shower. The accommodation further consists of 6 cottage suites, lavishly furnished and ideally positioned for maximum privacy, featuring separate sitting and living area, each accommodating up to 3 guests. All 9 new rooms offer top class amenities and a private balcony and have amazing views on sunset (= machweo in Swahili) and Mount Meru.

Since the 1st of October 2011, the new restaurant offers more space and privacy and a separate entrance and parking for outside guests. Dining, lunch and breakfast areas are both inside and outside and away from the guest rooms. Next to the renown daily chef’s recommendations, there is a limited à la carte menu to fit every desire. Taste the freshly made brasserie dishes accompanied by the finest specially selected wines. Their Michelin experienced Belgian chef prepares a fusion of exquisite European and African delights based on seasonal specialties. Just call or email to book a table for brunch, lunch, evening with friends or that special candlelight dinner occasion.

Onsea House and Machweo are perched on a hill providing unparalleled panoramic views across the Maasai steppe, Monduli Mountains and unrivalled spectacle of Mt. Meru; thé place to relax and rejuvenate before or after a Tanzanian safari and/or a Kilimanjaro climb. Discover this idyllic setting for spectacular sundowners and a truly African rural feel only 7 minutes drive from Arusha town centre and 30 minutes from Kilimanjaro International Airport.

The Belgian owners are happy to share their in-depth local knowledge. They can provide tips on cultural visits around Arusha and community development projects, including the iThemba Baraa Primary School initiative with 1450 pupils which are supported in the neighborhood.
