Stellar communication. Easy check-in and access to the apartment.
The apartment was clean and functional. The beds and sheets were really comfortable. (The funny looking chairs in the living room were perhaps a little less comfortable, though.)
Nice neighborhood. Plenty of bars and restaurants within walking distance and a grocery store around the corner. Nice parks (including a great kid's play structure in the closest one which worked out great for our 4-year-old) A little bit longer walk to the Metro than I might have wanted, but it was doable.
Overall - we had a great time!
