Siena's place was convenient for the 6 of us to stay at. Most was as described and Siena provided us with a lot of information before arrival. Check-in was easy. The washer and dryer in the unit was very useful but the dryer is a high efficiency dryer and does not dry very well. Fortunately, you can go downstairs to a coin dryer if you need, according to her directions.
I had an issue with the bedroom panel heater which made this clanking sound for hours in the morning and wouldn't let me go back to sleep. I contacted Siena about it but didn't get a response until the next day due to her being hospitalized at this time. I ended up reading through the guest info binder and searching the room for the on/off switch for the heater.
The property could use a little bit better lighting. There were 2 lights in the living room that didn't work even when I replaced the light bulbs with the ones provided, which I think might have been dead too.
The ceiling in the shower in the first bathroom looked like it had water damage and was peeling and bubbling off.
There was free beer, wine, and bottled water in the fridge, as well as pancake mix and coffee. There was a full kitchen with all you'd need to whip something up.
Overall, I'd recommend Siena's place for a large group visiting downtown Seattle, as it has a lot of amenities and convenience.
