Connie's place is exactly as described. It is super close to the convention centre and easy to walk everywhere. We were there for Bumbershoot and walked down to the Westlake Centre each day to get the monorail to Seattle Centre.
The location is just off Pike Street and we easily walked down to the Pike Place market and all the shops on Pine Street as well. The only thing to be aware of is that from about 6th Avenue it's an uphill walk to the apartment when you're returning. It's not too gruelling but just be mindful if you find this difficult.
The apartment is so easy to access with the August lock and there are two sets of keys for the duration of your stay. There is plenty of toiletry products for your stay as well. The bed is comfortable but the sofa bed is a little lumpy so it is ideal for shorter stays if you plan on using this.
Connie is a super accommodating host. She is quick to respond to our myriad of inquiries. Not only that, but she was happy for me to have deliveries sent to the apartment as well. This is so helpful!
