I don't usually comment on specific  ads but this one is clearly misleading. Today's DC ad for Alexa (Harmony Spa) is actually for a group of Russian providers who have been around for years in the Arlington (and sometimes Vienna) area. Whether they have external management, or are self-managed, I have no way of knowing. But it's an apt-based FBSM outfit and definitely not what one would expect from a true independent. As for performance, the reviews speak for themselves and my sessions were lackluster and overpriced. Also, they've been using the "college student Alexa" persona for many years so, unless there are multiple Alexas, she must be well into her post-Doctoral studies by now.
