I ended up booking a room at the Ramada tonight for the first time because I flew into PVG, was thinking about leaving on another international flight tomorrow, but I didn't want to stay in the Dazhong (I also haven't actually stayed there myself, so perhaps my bias against it isn't fully justified).
On the one hand, I'm certainly not wowed by the Ramada. On the other hand, it definitely lives up to the "peaceful neighborhood" billing that several others have afforded it.
The location is astonishingly bad wrt subway access (i.e. no stations on within ~9 km).
There is a mid-sized Lianhua across the street from the hotel.
For 外卖, you're looking at McDs, KFC, Dominos, some random Chinese restaurants, and most of the usual suspect chained convenience stores.
I happened to luck out on the airport shuttle front because I called just prior to booking the room, and one of the scheduled runs was minutes away. Otherwise, it is loosely scheduled service, and they want you to arrange it at least 2 hours in advance.
I guess my ultimate conclusion (at this point in time) is that while I'm unable to offer a glowing endorsement, I'm hard pressed to think of any specific examples of properties that better suit the layover mission, for those that hope to escape the airport environment.
