My parents and I had a wonderful two-night stay at David's place in early September. It was just perfect. The apartment was well-designed, uncluttered, and tidy. It is a ground floor unit, so it is a bit dark in terms of natural lighting (but plenty of light fixtures) - that just comes with the territory of a ground floor in an urban townhouse. There is a nice leafy view out the windows above the dining table. And, of course, being on the ground floor also mean no steps for carrying your suitcase up and down! The beds were comfortable. And David has thoughtfully provided all the amenities you could think of, from extra blankets and towels to a hair dryer and iron / ironing board.
The flat is located in a historic townhouse on a leafy, quiet residential street that is so close to so much. The original Intelligentsia coffee shop is just two blocks away on Broadway - a great neighborhood commercial street. Easy walking to the Belmont Station to catch the red, purple, or brown line trains. We went to a Giants / Cubs game at Wrigley one night and it was an easy 15 minute walk away.
David was an excellent host - always quick to reply to messages, sending thoughtful welcome messages, and also providing suggestions of what to do in the neighborhood and Chicago, often tailored to our specific interests (architecture, etc.).
I hope to stay here on another visit to Chicago. And I think my parents are convinced that AirBnB is a great option (this was their first experience).
