Great location! Most of what you want to do is within 15 minutes walking distance or less: Pike Place, Restaurants, Bars, Cafes, Pier 69 (for day trips to Victoria, Space Needle, etc. The neighborhood has a fun, safe, and friendly atmosphere.
I think Belltown is the perfect place for not being overloaded with the hustle and bustle of downtown and to experience the laid back culture of Seattle.
Rachael was a great host. She accommodated us on our schedules and made sure we had a list of the "best places to eat" nearby. The apartment is comfortable and has all the amenities you need.
