There is a tram station around the corner, but you will not need it because everything is in walking distance.
If you have a car, we can provide you a parking card at lowest price for this part of the town - CENTER. For one week it costs 26 € and you will have your car in front of apartment. And you can even park your car with such parking card anywhere in Zagreb, as well.

If you arrive by plane, there is a transfer from airport to Main bus station. From there you have less then 10 min walk.
Whenever we can, we wait for our guests at Main bus station. In any case we are on guest's disposal all the time.
