Changes

Take a regional train from train station ''Nyugati Pályaudvar'' to ''Üllő'' (550 HUF and 30 min ride). Walk ≈700m southwest on Deák Ferenc ut. till you reach the main road through the town Pesti út. Turn left (southeast) here and walk 2km along Pesti út to the large roundabout and MOL petrol station at the end of town. You can also hitch 100m past the roundabout on national road 4; although there's no shoulder, there is some space for cars to pull over and stop. Tried option 1 for 3 hours and then went to option 2, waited maybe 30min.
