I had the privilege of staying at Carolina and David's place while traveling to DC for a convention. Their place is well located to the Walter E. Washington Convention Center which is about a ten minute walk away. Their place is also well located very near a coffee shop, convenience stores, a "giant" supermarket, and a subway stop. The studio room is large with very high ceilings and is well and comfortably appointed. Communication was excellent too with the hosts and they showed great flexibility.
