We had a nice stay at Karl's place. The location is amazing. Close to metrorail and at about a 30 min walk to the monuments. The place itself is a little rustic, but cozy. The house has almost all the amenities. The only real issue is the footsteps noise from upstairs (which sometimes can get a little loud), but if you're planning to be out, you wont even feel it during the day, and it's quiet for the most part during the night. Stay here is recommended for museum and monument lovers!
