Tri's apartment was located in a very clean and young environment with Seattle University right around the corner. If you use Lyft (my preference) or Uber, you can very easily fly around the city. Tri's apartment is in a close enough distance that trips aren't incredibly expensive which is what attracted me to his place in the first place.
Walking is possible and we got a lot of mileage out when running around the downtown areas as well as Capital Hill, Squire Park, Seattle, Pioneer Square, etc, but keep in mind Seattle has some pretty intense hills at times. Sometimes you can get lucky and find these bicycles you can rent on the fly from your phone, but don't count on riding home up these hills on a 3 speed bike. You will need to use Lyft, Uber, or rent a car if you want to get the most out of the city on your stay.
Tri's bedroom and pull out couch were very clean and the bedsheets and comforter were wonderful. He also has a french press for brewing coffee - I used that a bunch!
There isn't an A/C unit in the apartment, but even thought I visited on some warmer days, it was very comfortable and manageable (I'm from St. Louis. It's no where near as humid and sticky where A/C is a must).
Overall, this apartment is great quality for what you're paying for - an affordable housing apartment within decent distance of a wonderful city. Tri was very quick with responding to any questions or emails that we sent back and forth and I truly felt that if I needed anything should an issue occur, he would have been there to help.
Thank you again for the apartment, Tri!
