My girlfriend and I stayed at Tri's for ~two weeks. Tri was extremely accommodating with early check in and his place was very clean. The location of the apartment is perfect for anyone new to Seattle. It is within walking distance of so many things in Capitol Hill. The ceilings above the beds and shower are kind of low so just be aware of that! Additionally, there is no A/C in the building (like the majority of places in Seattle), so it was a little hot during our last day when the heat wave began.
All things considered, our stay with Tri was excellent and we'd stay at his place again anytime!! Cannot recommend it enough! If you're considering booking, do it!
