Stayed here for ~10 days with my friend and quickly got comfortable.
The suite is true to the photos (both bedroom and bathroom) - limited floor space but we were still able to manage having our belongings out of our carry-ons. There is a closet so that adds some extra space. Bathroom was a nice size, two sinks and large shower. The room does not have AC but there was a small fan we ran throughout our stay. A few days into our stay we found a basic in-window fan so used that a few nights. Although we didn't mind, I'll mention that it does not match the width of the window so there are open gaps on the sides without any screen. Also worth noting - the main bedroom window does not stay open/up on its own. We didn't notify Robert because we didn't think it was worth our time given we only used the room to sleep/shower/get ready.
I was working remotely a few days while in Seattle so I used the kitchen/dining table on the main floor to work on my laptop/take calls and meetings. Rarely saw the other guests or Robert.
While staying in the home Robert was quick to respond and was flexible with dropping off/leaving luggage in the common areas since our flight times didn't align too well with standard check in/out times.
Robert has a handful of mini signs/messages throughout the home that serve as reminders. As long as you are respectful of the home you are in and understand you are co-living with the host and potentially other guests then you will enjoy your stay.
Location is about a 10-15min walk to the nearest Light Rail stop and about a 5min walk to Broadway which is a main street to catch several buses or walk around to eat/drink/shop :)
