I lived several years in the city and generally knew the area I wanted to be in for a return visit based on location of friends and previous favorite spots.
Kim’s place is perfectly situated near the 4th Street train station (which will get you most places).
Kim also provides the most fool-proof guide to not only staying in the space, but arriving, getting around, and local markets, etc. (if you lose the message, there is a hard copy awaiting you on arrival). And he very fast on response time if you have an issue (which I did...totally my fault and he fixed it pronto)
Great location. Great host.
