Top tier hotel not mentioned was the Fairmont, but agree with the low prices for this level of city. The Sun Yat Sen Mausoleum itself has lots of steps, but the entire park is amazing. Take some time to enjoy the whole area. The stair part is crazy busy, but walk the trails off to some of the other areas and it is beautiful, quiet and just as historically meaningful. You could easily spend a full day here. The street food in the old area of the city is awesome and easily accessible without language skills.
How is this as an entry airport vs. PVG? It looks like I'm going back to Suzhou for another 2 months this fall and HATE flying into and out of PVG. Is the metro to the train station fairly easy? I don't mind SHA since I can get a direct train from the airport or WUX since the taxi isn't long, but I HATE the drive to PVG!
Thanks
