My townhouse is in the Shirlington area of Arlington. It is within walking distance of restaurants, shops, theaters and a grocery store. The area is well serviced by the bus system which connects to the metro, or it is an easy drive into DC. My townhouse is in a nice complex close to walking/bike paths, a park and has remodeled bathrooms including a jacuzzi tub.
I have one cat who is easy to care for, but she can be very affectionate so you will need to be open to cuddling sessions. (I used to have two cats, hence the username, but this housesit would be for just one cat.)
