Help picking hotel in Saint Germain

I am going to Paris in August and need help deciding which hotel to book. After much research, below are my top choices with notes. My budget is around $500-600 a night.

• Pavillon Faubourg Saint-Germain & Spa - nice but small rooms
• Hotel Bel Ami - heard good things, but small rooms
• Hôtel Madison - larger room with city view, reviews are mixed since it looks like the hotel has new ownership and rooms have been remodeled recently
• La Villa Saint Germain des Prés - larger room with views

I know room size should not be a big factor if I'm not in the room the entire time. However, Hotel Madison and La Villa is offering larger rooms for around the same price with nice views. I have Platinum Amex so I would get extra Hotel Collection benefits for Pavillon Faubourg and Hotel Bel Ami (early/late check out, $100 credit, free breakfast, upgrade if available).

Right now, I am leaning towards Hotel Madison. The rooms and views look nice.

Any advice is much appreciated!
