Never, never again!!!
Let's start from the beginning - I asked for a room on the quiet side, I got confirmation that this is not a problem - I got a room side/front street, it was not quiet. There was no iron and ironing board in the entire hotel - after our very firm complaint, they bought it and delivered it to the room. Pillows - drama, hard and artificial, not possible to sleep o them- probably the cheapest range that can be found on the market. Waiter service - people without any experience, as if they were taken from a street round-up. No draft beer in the bar/restaurant. Bar- very small without any atmosphere. Check-out at 10.00!!!!!!!. There was no option for a later check-out - my friend wanted to leave his luggage for storage - the receptionist with disarming honesty said that he can't do it because there is no room to store luggage. Breakfast - really nothing special, very basic. The car park is a public, huge car park where cars of employees from companies that are around the hotel are parked - it is not a guarded hotel parking.
And finally, the best - all these attractions for only 200 EUR per night.
I have a very strong recommendation - change the name of the hotel to Grand Joke Zagreb because it's the biggest negative Joke I've had for last several years, sleeping in hundreds of hotels in Europe.
