Greg was a great host; he was flexible, friendly, and welcoming. The room was perfect for what I needed - a "home base" for exploring and a good night's sleep. With a key-code lock, I could come and go as I needed.
The mattress was very firm. The room (and bathroom) had large skylights; very cool for natural light. I'm an early riser so it didn't bother me, but it would be tough to sleep in too late especially during the summer.
Location was mostly quiet, though there was some construction outside during the day and it's close to a main road. It's walking distance to a nice strip of restaurants but having a bike was very useful to get to downtown and other neighborhoods. Greg stocked the room with maps/public transit info.
