We had a lovely experience in Grace's penthouse apartment. We inquired at the last minute (a day before our arrival) and she was incredibly responsive and accommodating. The apartment is charming and has lots of character (chandeliers in every room!). It was clean and in good order (aside from an appliance that we were warned needed repair). Lots of fun and quirky features, including a sleeping "nook" that our daughters adored. Beds were comfortable and there were plenty of extra towels and linens available. Private parking was available as well. The apartment is in walking distance to lots of shops, including a couple great places to get breakfast treats. We would stay there again if we found ourselves back in DC. Overall a good experience with good hosts.
