tldr; I recommend this place. Great ammenities and excellent location, with clean living space anf friendly people.
HI NW Portland was one of the nicer hostels I've been to. Suoer friendly staff who are always willing to give suggestions, and you share a room with three other guests. Bathrooms are a communaal space, with four of them on my floor - I never really had a problem with access to these bathrooms. Toiletries can be purchased for cheap at the front counter if you forget anything.
Ammenity-wise, there's events that happen everyday at the hostel, from live local music, game nights, or walking tours that allow for a lone traveller to connect with others during their time in Portland. The cafe is also a nice place to grab a quick meal or drink.
The hostel is located about 3-4 blocks from Pearl District, making it an easy walk to excellent breweries or restaurants in the city. I didn't really need to rent a car staying here since the public transportation was convenient and cheap, and walking isn't much of an issue for me (it takes about 20 mins to get to the other side of NW Portland, for reference). The 24/7 service makes coming back after a late night of fun not much of an issue, unlike other airbnbs where you may need to be mindful of a curfew.
I strongly recommend any traveller to consider staying here for their trip in Portland.
