You (and a friend) can stay in a guest room/library filled with books. The couch folds out into a twin-sized sleeper and there’s a queen fold-up foam for couples (or a twin air-mattress for those who want two beds). There are friendly dogs and cats in the house. You’re welcome to relax in any of the shared spaces.
The house is off 395, a 15-minute drive into DC. Lyft or Uber usually costs $7-$12 for most DC locations. The house is near many bus lines that can get you to metro stations.
