I go out of my way to stay at Fairmont properties because the concierge usually provides superior service prior to my arrival with my dog. I prefer the older properties because the walls are thicker and have better sound insulation As long as the room is clean, I'm okay with it being dated. Peeling wallpaper, dirty bathrooms (hair all over the shower walls) and a prior guest's underwear under the bed are pet hazards and just plain gross. Luckily the room is usually double checked (I request it in my profile) and I get a decent room.

However, when I am not traveling with my pet, I stay at whatever is the most convenient to the group I am traveling with & hopefully something that is part of an award program I'm in.
