This was a great place to stay for a semester in D.C. I was able to check-in smoothly, Quo always made herself available for any issues, and I felt safe and comfortable in the apartment. I am a law student and stayed for a full 15 week semester.
You have the entire apartment to yourself. Although it is connected to the rest of the home, Quo does not bother you or come downstairs for any reason. It is fully furnished with everything you need except food. (There is not a couch, just in case you want to have some people over, but there are multiple chairs and a small desk)
As for location, it is located about a 12 minute walk from the nearest metro stop (Rhode Island-Brentwood Red Line stop) which takes you into the middle of the city. However, there are two bus lines within 1-5 minute walking distance which will take you to Farragut Square or the monuments/museums easily. It's about a 30-min+ total commute to get to those places, so you would just have to plan your commute in advance.
This place is located in a safe neighborhood and I enjoyed my stay very much!
