The 264 and 264P bus is really close and goes to Cornelia, where the metro goes very frequently. The bus sometimes comes early and sometimes late so the schedule is hard to trust. Just wait at the bus stop and there will be one after a while. Otherwise you can take a 20-25 min walk directly to Cornelia, just follow the road.
They had a public refrigerator you can put your own stuff in. We used this to buy some extra stuff for the included breakfast.
