I would stay here anytime I visit DC. The place was just as described and bigger then expected. Lots of unmentioned extras. Our host's were kind, accommodating and helpful with everything we needed. The place was clean and the bed was AMAZING.
It was mosquito time of year but I don't know if there was anything they could do about that. If you are a late riser or are not use to little people this may not be the best place as the children start their mornings with enthusiasm.
But if that is not a problem for you then you won't find a better place in town.
