Both Karen and the apartment were great. The apartment was nice and comfortable and exactly as I expected it. Only a 15-20 min walk to most of the major attractions, and only a short walk to the metro to get you anywhere else you want to.
Karen was really helpful resolving an issue with getting the keys late at night and made sure our stay was pleasant. She was quick to respond to any questions that we had during our stay.
I would definitely recommend staying here if given the chance.
