We stayed two nights in a big room in the main building with a/c. The room was basic but this is ok and was what we expected from a homestay. The a/c works only at night.
The bathroom however needs renovation - it was shabby with a shelf that was almost rotten away.
The room was mostly clean (except there was waste in the toilet bin from the preceding guests and shabby pillows). There were no blankets on the beds and we had to ask for toilet paper and towels.
The location is good, close to the entry point of the Tangkoko Nature Reserve.
The food was simple and plenty but somewhat boring - for lunch and dinner there was always grilled fish, rice and only some variation in the vegetable side dishes. Breakfast was good.
For this room with air condition we were charged 350.000 IDR per night which we found way too much for rural Sulawesi in low season. For this price we would expect a better standard. So the price did not match the value at all.
The people where friendly and the laundry service was good.
They arranged a transfer by private car to Manado (250.000 IDR) to catch the ferry to Bunaken Island, but the driver was 1 1/2 hour late so we missed the public boat. The driver promised to find another boat for the same price but there were apparently none. So we lost one day of precious holiday.
It is not guaranteed that you can visit the Tangkoko Nature Reserve with Reni, the guide from the Tarsius homestay, as the nature reserve office will assign a guide to you. Our guide was nice but spoke very little English, but at the afternoon walk we were also accompanied by another guy who spoke good English.
Our experience of the Tangkoko Nature Reserve itself was good. The forest is beautiful. In the late afternoon we saw the lovely Tarsiers and during the morning walk we saw the black Macaques from very close. Unfortunately it was raining badly so no birds or other animals to see.
