Our family of four (3 and 5 year olds) spent three nights and it was just what we were hoping for. Patrick and Jen were very responsive and helpful both before and during our stay. Location is close to the metro and walkable to many restaurants and a grocery store. They provided a binder with recommendations, maps, and tourist info and provided additional recommendations when we asked. All their recommendations were great and made our trip better (like the butterfly exhibit at the Natural History museum).
The space is well decorated and outfitted basic kitchen ware. The provided bread, milk, orange juice, and eggs were a nice touch.
Other reviewers noted noise, but we did not have any issues. It's in the city, so you'll hear outside noise you'd expect, and their family lives upstairs, so you'll hear noise you'd expect--though honestly we didn't feel this was an issue at all and either they're really careful about noise and/or their kids are normally way quieter than ours.
The house is located in a transitioning neighborhood, so you'll see a range of housing from renovated homes (like theirs) to low income housing and all in between. But the neighborhood seems well maintain and we never felt unsafe, even when walking back from the metro after the sun had set.
Overall we would definitely recommend staying here.
