First, Alex is a great host. Very friendly and communicative. She answered all of my questions and gave lots of hints and tips about DC. The apartment is very nice, exactly as advertised. Spacious, comfortable and well equipped. Located in a very quiet and safe residential neighborhood, but also an easy walk to shopping, restaurants and a Metro station ( DC's Metro system is great!! ). It's about a 20 minute walk to the US Capitol.
I would not hesitate to stay here again and would recommend this apartment to anyone visiting DC.
