It is great place if you are looking for the hotel at the center of Zagreb. You can get the famous market, church and restaurants just in 3 to 5 minutes. Across the street, there are so many good cafes and restaurants located. If you need any further information on the travel, you can go to information center just around the corner.
However, there is no reception because it is an apartment. You have to contact the manager before arrival at the address through viber or any other SNS. The other thing I did was to ask person at the information center about how to meet the manager. Other than that, it is good place to stay at.
