We own at GRC and have stayed there many times. Have never stayed at TL, so cannot comment on them much. The units in the GRC don't have washers/dryers, while those in TL do. However, there are free washers/dryers in laundry rooms distributed pretty widely throughout the GRC. Whenever we've needed to use them, they were empty. Pluses for the GRC are larger size units, the concierge for both GRC and TL is located in the GRC (I find it helpful to work them face-to-face), a beautiful and uncrowded exercise area, a fabulous sauna/steam room, and a full service spa, all right in the building. Both buildings were built at the same time, so age is not a difference. The GRC condos just underwent a minor renovation over the last few months. I'm sure you'd have a great time at either GRC or TL.
