We had a great stay at Sheila's apartment! It has everything you could possibly need (great bathroom with towels, toiletries, etc., a mini kitchen, coffee, tea, air mattresses, extra blankets, pillows, sheets... I could keep going)
The apartment is beautiful and spotlessly clean, and Sheila and her family were quiet and easy-going. The location is a really nice residential area right off of H street, which has a ton of nice places to eat and cool pubs (I'd recommend The Pug and Bullfrog Bagels)
I can't recommend this place enough!
