My friend and I stayed at Karen's for 9 days. Everything was wonderful and perfect for us. The house was clean, the bed was comfortable, the kitchen was filled with all necessary items.
Check-in and check-out time are flexible which were extremely helpful for us as we arrived and left DC very early in the morning. Mary, the lady that helped us to check-in & check-out, was always joyful and energetic. She made us feel like home.
This place is only 4 min walk to Potomac Metro Station (for Blue/Orange/Silver line). It is extremely convenience.
In addition, Karen responded very quickly to all of our messages. During our stay, she always ensured that everything is good for us.
I definitely choose to stay in Karen's place again if I go back to DC.
