I must say, Marvin's Seaside Inn is one of the few good hotels in Naval, Biliran. I booked 2 rooms for my family, and both rooms were spacious. It is located near the centre (just 5 to 10 minutes away from the port area). The place itself is laid-back, perfect for those wanting a homey stay. Plus, they've got complimentary use of their pools. Maybe more on hotel maintenance, especially the pools.
