Everything was perfect - one of my best Airbnb experiences - thank you!
Free parking on the street is only available on Saturdays and Sundays with limited spaces only (not surprising in the center of a city as Prague but good to know).
During the week parking on the street is minimum 1,6 €/h (24 hours a day) and only for a time period of maximum 24 hours. After this time you need to buy a new ticket. Online ticket is possible.
