Jeffrey’s place is great! Its exactly what is listed, its an basement apartment unit that is fully furnished with a small living/kitchen room, a bathroom and a small bedroom. The apartment is small but has everything you need. The location itself is great, its about a 20-30ish minute walk to the National Mall (we chose to walk but I know there is public transportation near by). One of the the reasons we chose Jeffrey’s place was that it had a full kitchen equipped with basic kitchen supplies. We'd often stop by Trader Joe's and pick up some things to cook for dinner instead of eating out(Trader Joe's is about 10-15 minutes walk away).
Like other reviews mentioned, I think this space is more suitable for 2 but three can definitely squeeze in. There is some foot traffic from the upstairs unit so bring earplugs if your super sensitive to sound, personally it didn't bother me that much. Btw Jeffrey asks that you take out trash and leave sheets and towels near the washing machine when you leave.
Would highly recommend staying here!
