Jeff's place is great. It's on the smaller side, and I wouldn't recommend coming here with more than two travelers, but it's extremely clean, in a fantastic location, and has a very responsive host. The kitchen is smallish but perfect for cooking breakfasts or simple dinners, the bathroom was spotless and had a nice shower and the bed was comfortable.
As other reviews flagged, being on the second floor in Belltown there was a good bit of outside noise (we had the window open because it is summer), but it didn't really bother us all that much other than the occasional fire truck or ambulance. Unless you need silence to sleep, it shouldn't be much of an issue.
The only issue that arose was the dishwasher leaking, which occurred because a pipe wasn't connected. As mentioned in the description, the apartment has a water alarm which was instantly tripped. What was not mentioned was that there were in fact four water alarms. We had to search for the others and were only able to find 3/4, so we had to call Jeff, who responded quickly and was at the apartment within 15 minutes to find and turn off the last one. In all, the alarm was probably ringing for about 30-45 minutes and was earsplittingly loud. This seemed like a fluke issue, but the timing was not ideal, occurring in the middle of a series of work calls.
