Gregory's place is everything you need in Portland. It's close to everything, without being downtown. But if you want to go downtown, Gregory's made it super easy with simple directions to transit and local bicycles. It's proximity to great tourists spots is also a big draw. His place is just a few minutes from Voodoo Too! Or the super quaint Hawthorne district.
The room has lots of light so the only thing I'd recommend is to bring a sleep-mask if you're not an early riser ;). The AC works well and the bedding is fresh and clean. Plus, if you happen to run into Gregory, he has lots of stories from his many travels abroad.
