This is the place we stay at. Not as smart as the one above, small balconies overlooking Marina Grande and apart from a nearby loud church bell, a quiet location. You would need the two bedroom apt as I think using the living room as a bedroom would be a bit cosy for four. About 5 min walk to the old town streets and 10 mins to Piazza Tasso.
