Receptions were nice and patient to explain and check the cars before giving the car but if they could tell renters who were not local how to park on the street, it would be much more appreciated!
User friendly! Nearly solve problems that might have.
For parking on Belgrade Street, u will just need to buy a local pre-paid SIM card (I used the Telenor), put money in it and then send your car plate via sms to the according number which they show on the signage. Oh! It’s free from every Saturday 2pm to Monday 7am.
