The apartment provided by Nick was beautiful. The bed was superbly comfortable, having fridge space and a microwave was incredibly helpful, and the kitchenette area was great. (Breakfast and fresh fruit were surprising benefits and appreciated!) But above all, the bathroom and shower far surpassed any hotel amenities. I could rave about the shower for much longer than anyone would appreciate, but seriously-- it was great.
The house is in a great neighborhood within a stones throw from a nice pub with good beer, within walking distance from several good restaurants, and within a 5-10 minute walk from the subway station (bus stops and bikes were even closer).
As a host, Nick went above and beyond to accommodate us and make our visit to the windy city a good one. We were visiting the University, and he gave us a crash course in public trans and the city in general that we couldn't have done without.
This was the BEST Air B&B. 10 out of 10; five stars; would definitely stay again.
