Rooms at the Grand Mercure Singapore Roxy is aging but functional. I stayed at the Studio Suite, which had warm earthy tones, low lighting, a marble tiled bathroom, and a carpeted living room. Said to have a "chic minimalist zen" vibe, I didn't quite feel it, although I still decently enjoyed the experience.

As I said, I would highly recommend getting Executive Lounge / Club Lounge access whenever you are on staycation, then you can just stay in the hotel all day!
