We just completed an excellent weekend stay at the Westin Georgetown. My wife and I were in town for a wedding and had our 18-month son with us. The hotel is a busy one, but the service level was consistently good. In addition, our room was very nice and spacious (the 1-bedroom King suites are worth a splurge).
Most impressive was Lana Kim, the Stay Ambassador. She reached out in advance of our stay to ask how she could help and then followed through with getting us a quiet and spacious room, per my request. Lana went above and beyond to make sure that we were well taken care of. In addition, the front desk was able to hold our room and accommodate a late check-in when we were delayed in traffic.
All in all, a wonderful stay. The hotel is also great for work travel (I had stayed a few times before as well).
