The apartment has a good location i Seattle at Capitol Hill, 10-15 min till city center and there are some nice supermarkets and restaurants near by. The neigborhood is safe, but there are some homeless people near the supermarket. Be aware, that the apartment is in the basement of the house and is really dark, with almost no sunligth getting down there. Also you can hear people walking around in the apartment upstairs.
We never met Tricia and Isaac but they where very communitive, and answered very fast.
All in all, it was okey, if you do not spent too much time in the apartment...
