Onsea House & Machweo is a charming boutique hotel on the outskirts of Arusha, with comfortable rooms, views over Mount Meru and a lovely spa. Whether it's the start of your trip or a relaxing place to unwind after your safari, this is a great base.

There are thirteen rooms in total, four in the main Onsea House, and six cottages and three suites at Machweo, all set in the extensive and beautifully manicured gardens. The cottages have been designed thoughtfully to make the most of the space within – arranged in pairs overlooking the gardens they are comfortable and spacious, with muted colors and a slightly different design in each room. The rooms at Onsea House house feel a little smaller and darker than the cottages in the garden but it is still a lovely option for families, with its own swimming pool, terrace and garden.

The atmosphere here is one of total relaxation, with plenty of areas to relax and a large terrace on which meals are served. The food here has a deservedly excellent reputation – Axel, the chef-manager, is part of the Janssens-Onsea family who own the hotel, and creates the most delicious meals for his guests – as you would expect from a chef who worked previously at a Michelin starred restaurant.

There is a swimming pool at Onsea House and another at Machweo, offering plenty of space to relax and unwind in the Tanzanian sunshine. There is also a fantastic spa, offering pampering treatments as well as a sauna and steam bath.


The hotel splits into two areas - Onsea House and Machweo. The house consists of 4 double suites opening onto the shared terrace. Machweo has six cottages, set in pairs amongst the gardens, and three beautiful suites. Several of the cottages and suites interconnect, ideal for families. All rooms have an ensuire bathroom with shower - at Onsea House there are combination shower/bathtubs, whilst at Machweo the cottages have showers only and the suites have a bathtub as well as a shower.


The Michelin experienced Belgian chef, Axel, prepares a fusion of exquisite European and African delights based on seasonal specialties.

Location & Directions

Arusha, Tanzania

Onsea House & Machweo is perched on a hill providing unparalleled panoramic views across the Maasai steppe, Monduli Mountains and the unrivalled spectacle of Mt. Meru.

When to go

Tanzania is a large country, with a varied climate. Generally, the long rains run from March to May - the temperature is warm and the humidity is high. June to October is the long dry season, and the short rains are in November and December, much lighter than the long rains. January and February are again dry (the short dry season) so this is another good time to visit.
