My girlfriend and I rented here for a 1-month medium term stay in the greater Seattle area.
Let's start with the location - Wallingford is superbly located close to Fremont and a very quick drive to downtown Seattle. It's a very walkable neighborhood and having Green Lake Park literal blocks away was super convenient for getting out for runs and bike rides. Some aspects of the neighborhood are a little grungy and disheveled, like the occasional shouting homeless man or sections of rougher pavement, but we never felt in danger and the huge selection of local restaurants and charming neighborhood houses more than made up for it.
The apartment was very clean, easy to check in, and quick to settle into. I want to give a special shoutout to Miles (one of 2 property management coordinators) for being so active on communication and very quick to respond to questions. We had a crooked dishwasher on checkin that was fixed fairly quickly and had no other major issues. It's one of 6 units in the same building that are all rented out for short term stays. If you're looking to stay here for longer than a week, it's worth mentioning that the kitchen only has 2 induction burners, no oven, and a smaller fridge with a narrow top drawer freezer that can often freeze food put on the upper shelf below. We happened to stay here during Seattle's unprecedented "heat dome" that brought temperatures up to 106 degrees and the building provided 2 portable AC units that really saved our bacon. The building itself does get pretty warm during the day and can be a bit ovenlike without AC - which again is not an issue for 90% of the year in Seattle.
Overall I'd say this was a decent to good stay with no dealbreakers or major complaints. It was a great home base to explore around Seattle for a month. If you are looking for a more curated or unique Airbnb experience, maybe consider elsewhere - but for all other purposes this place provides everything you need and nothing you don't!
