This was mine and my girlfriend's first trip to Chicago. We had a wonderful time. We stayed a total of 5 days.
Positives: The house was a good size and short lyft drive to downtown. The neighborhood was not scary or dangerous but be mindful of walking around alone at night. Extremely comfy bed and couch. Lucien was very responsive throughout the entire process of getting checked in. Also there is a great supermarket called Marianos walking distance for supplies.
Negatives: If you are staying for a long period of time and are like me and like to cook, be weary that there is no kitchen. I was hoping that we would be able to cook the majority of the time there to save money but Lucien provides a few kitchen appliances that helped. The toaster oven was very helpful so we got creative. The bathroom has funny septic smell at times. The dog upstairs is a little talkative and can be very loud when he is next to the connecting stairwell. Sounds almost like he is in the same room. There is also a camera in the main living room which is a little invasive.
Conclusion: The house and host are great. I would stay again for a short duration. Anything more than a day or two I would most likely look for a full size place with a full kitchen.
