1. Slight negative is the trmendous oise the room doors make when falling shut , especially when not too considerate guests walk out of their room at early hours and let the door slam waking up most rooms around theirs; maybe doorstoppers can dampen the noise a little ? Had to pay for extra late check out ( out at 3 pm instead of 12 ) which seemed strange as I am a HH diamond and hilton never charges me for late check out so I asume this was because I am only Hyatt Gold and not higher level of frequent guest ? All in all we had a very nice stay and certainly this is a hotel to return to when in boston for my next visit .
