The unit was spacious, clean, and in a perfect location. So many little conveniences were thought of, too! Communication was quick and easy. We visited during spring break and the park across the street was full of cherry blossoms. Loved walking to the Mall, and loved the off-street parking for those times we ventured farther away and needed to use our car.
It was 5 of us, two adults and kids aged 8, 10, and 17. My son ended up using the provided air mattress instead of the fold out sofa bed so that he could sleep in the bedroom, but he found that comfortable as well. The only tiny thing to note was that the water heater seemed pretty small. We spaced out our showers to avoid cold water.
Overall, we had an absolutely wonderful stay. I'd recommend this rental to anyone, and would love to come back to it on our next DC visit!
