Plush is a wonderful place to stay in the Palisades neighborhood of DC. We stayed for two weeks, visiting family in the neighborhood, and it worked out very well. The place is well-equipped with good appliances, household goods, and plumbing. It is also very clean and quiet. Piano lessons go on upstairs, but we actually enjoyed that the few times that we were around. Matthias is very responsive without being at all intrusive.
Be sure to visit Aracosia, the new(ish) Afghan restaurant across the street
