Budapest - Gyergyótölgyes utca

Large parking lot near public transport hub. It is a "park and ride" facility. It is open 24 hours a day. Parking is free. There is security stationed near the gate who didn't even look up when we drove in. The carpark is flood lit at night. You can catch the number 19 tram to Buda (royal palace) or 49 tram to the pest side of the river (Synogue etc). You can purchase tickets at the nearby train station. We used a 24 hour unlimited travel pass (budapest pass) for 1650 HUF.
