The Sheraton Zagreb is a breath of fresh air compared to the Westin - here are my impressions and photos:

Note: I was not offered nor did I ask for (due to flight schedule) late checkout.

Pros:

• Upgraded the morning of arrival to an Executive Suite and was assigned a renovated suite with 2 full bathrooms
• Bed was fantastic - soft and clean linens, plush mattress, plush covers, plush pillows
• AC WORKED WELL!!!!!!!!!!!!!!! (admittedly, it would need to as the windows can’t be opened)
• Living room couch was comfortable
• Blackout curtains were super effective at darkening the room, even after sunrise
• Lounge on first floor was a nice space - had good cinnamon rolls in afternoon (no breakfast service) - evening happy hour from 6 to 9 - didn’t see any new desserts besides more cinnamon rolls
• Needed to pick restaurant breakfast as welcome gift (technically brand standard), but restaurant breakfast was good - order omelet from server - tasty and cheesy - no pancakes or waffles, though (maybe you can order from server?)

Neutral:

• Shower pressure was fine (not amazing, but better than the Westin)
• Welcome gift of 6 apples, tea, wine, and tea biscuits was a bit funny

Cons:

• Took 3 attempts to get working keys - first didn’t work in elevator, 2nd set didn’t work for club lounge

I would come back due to the comfy bed and working AC.
