George is a wonderful host, and he is very clear about what the house rules are (so please read through the details in description of the hosting). We all know you can't predict every single situation that may happen (though George is doing everything possible), so direct communication to him is definitely the key to resolve any questions.
The room description is absolutely accurate, it's mostly for staying overnight but not for work because of its size. Whole apartment is very clean, well maintained. Location is just great - you can get to the Loop in about 40 min taking bus 146 which stops a block away from the apartment
