My friend and I visited Bohol largely to see the Tarsier Sanctuary and were looking for a convenient base for a two night stay.
The Gabriella B&B was able to fulfil our needs, providing low cost, clean and functional rooms and a basic, but serviceable breakfast (pancakes, cooked and cold meats and omelettes cooked to orders placed the night before).
Location wise, the B&B is near the airport, and the tour operators were able to pick us up from our location and take us to the Sanctuary and the chocolate hills, although the B&B itself is not very near these attractions. It is however a half an hour walk from a shopping centre with various restaurants, a cinema and a supermarket.
To note, the air conditioning unit in the room is REALLY loud. And I mean REALLY loud, it sounded like you were on a runway with planes taking off over you during the night! You are kept cool, but at a price! I would therefore give the B&B a higher rating if a quieter temperature control system was implemented, but it is still a good base for exploring the sites of Bohol.
