Maria's place lived up to the description, as well as all previous positive feedback. The place itself was cozy, and as hosts, Maria and Dan were genuine in their welcoming attitude. The back patio was a great bonus - we could not have imagined what a nice spot it was. Overall, this was a great place to stay for our family of four. I can't say if there were high chairs present, as we brought our own (borrowed from local friends/family), but Maria and Dan were quick to help us settle in by getting out some old (classic wooden!) toys for our son to play with.
Finally, the location of Maria's place was nearly perfect for us. It was quiet, with easy parking (which can be rare in DC), and a short walk to a local playground as well as Rock Creek Park. Major amenities are not far off, either.
I would recommend Maria's place to any small family, couple, or individual looking for a quiet, comfortable place to call home while visiting DC.
