Overall, this is going to be your best bet for an affordable place near Georgetown. Hands down. The space looks just like the photos, and to be honest, is one of the trendier interiors of the generally older architecture in the area. Elizabeth is a phenomenally kind host, so that should seal the deal.
Pros:
The space itself is updated, and the best you'll get for the price. The location is perfect for someone visiting the university. It's right near where plenty of administrators and students live, so you're not too far away. That being said, it'll add a few more minutes to your walk if you only care about the downtown area. As aforementioned, Elizabeth is a great host, she took care to have some breakfast items for me and kept the space very clean and bright (especially important since it's a basement apartment).
Cons: Since this is a basement apartment, it has no kitchen. That being said, there was an ample sized fridge and freezer as well as a microwave, so unless you really need to cook constantly, you'll be fine! At times, you can hear footsteps/noise from the floor above, but that is no large problem -- it still has a feeling of plenty of privacy.
