I spent one week at Carmen's lovely O Street apartment while in Washington on business. The apartment is perfectly located in a safe neighborhood and a safe building (with two other apartments) and close to the Dupont Circle metro, restaurants, cafés, shops, and Farmer's market. Moreover, it is a short walk to the White House and Georgetown, if you prefer to explore the city on foot. Everything you could want when away from home is in the apartment, including a washer and dryer, and of course, Wifi! It was impeccably clean and welcoming. Carmen and I were in close touch before I arrived and checked in when I landed. She left some tips about the neighborhood that were helpful. I certainly hope that it is free when I return to Washington on my next trip!
