Great place for groups! Five people stayed here and it was wonderful. Plenty of room! The area is super walkable and lots of things to do nearby, not to mention how central it is to the other areas in Portland that you might want to uber to. Minor downside was that there were only two bathrooms and one had a shower and the other had a bath, which wasn't super convenient but not a big deal. Would definitely stay again!
Finally, we didn't have kids with us but there was a bedroom for kids/babies and also a playroom that I imagine would be great for families.
