Be aware that AirBnB has the location wrong on their map - it's not a five minute walk southwest of the Omni Shoreham Hotel, it's more like a 10 minute walk due east. I've never seen such an inaccurate map location on AirBnB, but they refuse to change it.
Anyway, the house is great, very beautifully decorated with art, antiques, rugs, statues, carvings, a really nice art collection. Gary was super helpful and responsive. Guests stay on the 3rd floor of the house, which is quite private since the place is so big. The front bedroom has a lot of street noise since it faces Calvert, so I used earplugs, and the back bedroom faces the back, which is very quiet.
