Not really a traveling qns but is there any affordable staystation hotels in Singapore? Thanks for your recommendation in advance!

I recently had a staycation at Carlton city hotel. Went on hoteldeals.sg and filtered for 5 star hotel in singapore and chose the cheapest with breakfast! :) then I called the hotel and told them it's my wedding anniversary can they do anything nice. So they bumped us up to a room with a tub and gave us a plate of fruits. ;)
