Ok I gave 5/5 for all four criteria, although some could perhaps be 4.5/5. The service is excellent when you combine the Routes 216, 219 and 220 to get to certain destinations where all three Routes crossover (eg. Domain Interchange, South Melbourne; Queen St, Melbourne; Paisley St, Footscray; Essex/Ashley St, West Footscray; Sunshine Railway Station). Together the combined services are run every 15 minutes during off-peak weekdays. The buses are always oquite clean and comfortable. During peak periods (from city on weekday afternoons, to city on weekday mornings) it can be uncomfortable to travel despite extra buses and more frequent services at these times. They generally run on-time, but there have been rare occasions when a bus was due but never showed (driver gone fishing?). I am glad to have this service near my house because it is so convenient.
