It's a lovely apartment in an excellent location. Comfortable for our family of 5 (2 children + Grandma). Well stocked kitchen if you want to do a little cooking. Very close to Metro, grocery stores, and great playground. If booking in summer, know that there's no AC or fans. We happened to be there during unusually warm weather and the apartment did get uncomfortably warm.
I found Maria's team to be responsive. However, it did seem like I was communicating with someone who didn't live in the area. It was just a different experience other Airbnb's I've done before with hosts who just have a rental or two.
Overall, we had a good stay and I would book the place again.
