Personally, I enjoyed the Queen Anne neighborhood in Seattle. There are many townhomes & condominiums to choose from. As a single professional, your employee might enjoy all of the offerings this neighborhood has to offer. There are tons of restaurants, cafes, and grocery stores all within walking distance. The Seattle Center & Pike Place Market are also within walking distance.
I would recommend staying close to I-5 when looking for a townhome. Traffic in the city is difficult to navigate, so being close to the freeways will help lessen the stress of commuting to and from work.
