Just stayed @Residence Inn Mystic... booked award stay when it was still Category 4. Overall, the stay was ok. However, the whole place needs refurbishing.... older furniture in rooms, etc. Plus, they have some quirky policies in the "guesthouse"/breakfast room. There is a sign that states "all food must be consumed in guesthouse" with personnel standing there watching your every move. Second sign along the lines of please be considerate of other guests when taking portions. The food display was lacking too... just a couple yogurts, fruit, etc.... was not an abundant array as in other RIs. However, the location was a good one. Be advised that per housekeeping the only rooms with stoves (not stovetop) are the 2 BRs. I have stayed @other Cat 4 RIs, and do not feel the Mystic RI deserves the Cat. 5 designation.
