Why guanidine acts as a good base?

Answer. It is a highly stable +1 cation in aqueous solution due to the efficient resonance stabilization of the charge and efficient solvation by water molecules. As a result, its pKa is 13.6 meaning that guanidine is a very strong base in water; in neutral water, it exists almost exclusively as guanidinium.
