This might just be the best deal you can get in DC! Not only is it ideally located in a well-maintained building - I didn't even have to take the metro once - the apartment is spacious, sparkling clean, and the amenities are incredible. Last but not least, Silvia was simply amazing as a host, very attentionate and constantly making sure everything was OK; before and during the stay, our communication was great.
If you have the opportunity to stay at Silvia's, look no more!
