Maricel's house and hospitality were top notch, this is easily one of the all-around best AirBnB experiences I've ever had.
The house was lovely, not too large but not too small, with modern amenities, comfortable bedding, and a well stocked kitchen. The decoration was very tasteful and the space very much felt like a home, not the straight-from-Ikea cookie-cutter houses that are pretty standard on AirBnB these days. The location provides easy access to lots of nice amenities, a grocery store, some of DC's prettier neighborhoods, and the DuPont metro a few blocks away.
As for the hosting, it was superb! Maricel was super communicative in the run up to my stay, helping me plan out a few necessary details for my long-ish stay at her house, and gave an exhaustive and very useful walkthrough of everything I needed to know in the house. She was also very easy to reach throughout my stay and always seemed genuinely interested in my having a good time.
I will definitely book at Maricel's place again if/when I return to Washington.
