We stayed in the penthouse suite for a week and enjoyed every minute! We were out exploring most of the day, but enjoyed mornings and evenings on the patio admiring the view and watching dogs play on the rooftop across the street. The location is perfect for walking down to Fremont (although there are steep hills - as with most of Seattle - so be aware if anyone in your group has physical limitations), or taking a car/bus into Ballard or downtown. The neighborhood has excellent restaurants and bakeries, coffee shops, etc. Parking is convenient and safe, and the building itself is very secure.
We didn't use the tub, although it looked pretty inviting! The bed and furniture were comfortable and the kitchen was very well-appointed. Laundry and dishwasher worked perfectly and there was plenty of soap on hand for multiple uses. The closet had tons of hangers, which are usually a PITA to share. We were even able to hook up our Roku to watch a few movies on quieter nights where we needed a little vacation from our vacation.
I would highly recommend staying here, and we'll definitely be back next time we're in Seattle!
