City Comfort Inn (Kunshan High-speed Railway Station Renmin Road)

Location was perfect and also my initial consideration, right at the center of city. No much to expect except for those standard items example - service, cleanliness or comfortability therefore to my surprise, the rooms were cosy and clean (guessed it’s because they were newly renovated or not long ago) but, but except for some minor hiccups example - air conditioning controls (remote and wall mounted) + room WiFi needs pre-logging on before connectable (used my phone hotspot to fix problem)! Everything was fine until the next day slightly before checking out, they cut off my room electricity abruptly half an hour before checkout time! Imagine if you’re still using the bathroom! This needs serious attention as I have never encounter such scenarios before, in my entire life experience of travelings and staying in hotels. Never. Of course my booking came with the “late checkout privilege” so why the rush? Oh and they did offer an upgrade of room (when checking in) but, but with additional charges! Wondering if these misunderstandings were “intentional” or caused by miscommunication between the hotel management and platform, a sales technique? Please clarify: rewards enjoyable/ available after booking, if possible thank you
