Kepler-88 is a G-type star 1,230 light-years (380 parsecs) away in the constellation of Lyra, with three confirmed exoplanets. SIMBAD lists a subgiant spectral type of G8IV, while other sources give it a main sequence spectral type of G6V. The latter is more consistent with its properties (it is less luminous than the Sun).
