I gave 5 stars because Marco was an *excellent* host and we had a pretty comfortable stay/experience overall. I'll start with the positives and then describe a few things to be aware of because I rely so much on the written reviews when deciding on a rental.
My brother helped me select this location as he used to live in Chicago. I was traveling alone with my 2 sons w/o a car, so I wanted a place that would be safe, quiet and convenient. The location definitely felt safe and was extremely convenient to the Fullerton station and a Divvy bike station, so it was super easy taking the train/bus/bike almost everywhere. I also agree with one of the other reviewers who stated that the noise from the train running so close by was surprisingly quiet. It was more like an ambient "whoosh" sound when it would go by (assuming windows/doors closed), but not enough to prevent or disturb sleep as there are no horns, whistles, bells or vibration. There was also no noise that we ever heard from neighboring homes, businesses or passers by.
The apartment was well appointed and clean with very comfortable beds/bedding/furniture and a nice desk area, and the floor plan has been truly maximized to make the most of the space, which is essentially 2 rooms and a large bathroom, which had everything we needed for our 1-week visit. The hosts also included breakfast items and other amenities, which was a nice touch.
For our situation, the floor plan was fine, but I could see it being tricky if multiple households are sharing this space because one of the bedrooms is also the common area. Also, kitchenette is best for making basic meals, so nothing extravagant. Although the location was nice, I did experience noise disturbances from trucks that would drive by or be backing up in the alleyway in the morning, so just be aware. Otherwise, a very pleasant stay and I would highly recommend as long as these "issues" are not deal-breakers!
