Charlotte's place worked well for a couple of older travelers. About 7-10 minutes to the metro. Decent, quiet neighborhood. We felt safe there.
Bed was like a Cal King and very comfortable. Kitchen was well equipped. French press coffee maker, electric kettle, toaster,etc. Microwave was not easily accessible, though we didn't need it.
Plenty of hot water for dishes and shower.
Nice and airy with large windows in living and bedroom areas.
Highly recommend it!
