We enjoyed our stay at Keith's Queen Anne apartment. The photographs are very accurate. The apartment was clean and the appliances were all very nice. It was perfect for me, my wife, and our 10-month-old daughter. She slept in the playpen we brought, and it fit inside the bedroom with us.
The location is good, it's a very quiet residential neighborhood with a short drive to the Fremont or Queen Anne neighborhoods. However there is nothing within a short walking distance, and the hills make it difficult to push a stroller around. However if you have a car with you it's convenient and close to a lot of cool areas. You have to walk up a lot of stairs to get to the front door, but street parking was not an issue at all.
We only had two small issues that could be addressed. The main issue we experienced was running out of hot water, I think because the water heater is small. It wasn't a problem for me, but my wife likes a long shower and it got cold on her before she was done. And the other minor issue is the heater is tough to maintain. The heat works great, but thermostat seems to only understand "on" or "off", so you might be a little cold or a little too warm if you neglect the thermostat.
But neither of these issues were deal breakers for us. We enjoyed our stay in Keith's apartment and would recommend it for a couple with or without a small child, as long as you have a car with you.
