Georgetown location, mystery charge
Location, location, Georgetown location is the Latham Hotel's strength. It's an older property with issues that have been noted in many reviews. I arrived early, a bit past 1 pm, check in was a breeze. My clean room this time was a comfy king corner room facing the canal and side street. Yes there were wall paper issues, the bathroom sink is loose, if I'd paid rack rate, I'd have been unhappy. Bathrooms are for one person at a time, towels and soap adequate. Since the weather was gorgeous, I spent little time in my room, TV worked OK, didn't use parking, workout room or outdoor pool. 
Georgetown is noisy on M street, the windows are thin, and yes, the garbage trucks are out early. If you got a good deal with an on-line booking company, don't expect to get a top notch room. This isn't a 4-star hotel nor a "boutique" like a Kimpton property. 
I like that it's close to public transportation, shopping, fun sights, and good eating at many price points. As a single woman traveling alone, I felt safe at the hotel. 
After caring for my bags, the bellman got me a towncar to the airport. My experience was positive at the Latham. 
After I got home I had a mystery charge appear, and it's taken several calls and emails to resolve it, they finally responded and say that they'll credit my account, it isn't there yet, stay tuned...
