Stayed for a month in October 2022 and overall had a decent experience.
The good:
Overall, the apartment is a nice one-bedroom, with modern amenities (kitchen, bathroom, etc.). It was very clean and well-stocked for a long stay (kitchen appliances and cookware, toiletries, etc.). The location is absolutely great! You're right by Lincoln Park, and close to many restaurants, coffee shops, grocery stores, all within short walking distance. TJ was very friendly and very easy to communicate with. She was quick to resolve any issues that came up during my stay.
The not-so-good: To start off there were a few maintenance issues that had to be resolved after my arrival. The heater didn't work and required an electrician to come fix it. Some lights were out, the shower was clogged, etc. Unfortunately that meant that I had to spend the first few days of my stay coordinating with the host and the electrician to perform the required maintenance.
Also very unfortunately, the building next door began exterior renovation a few days into my stay which lasted throughout the entire month. That meant scaffolding about 6 feet away from the bedroom window and drilling / sanding noises throughout the day. I realize that the host had no way of knowing that would happen and no control over the project, but overall that did not make for a pleasant and peaceful stay. Just bad luck. Maybe just make sure the renovations are over before booking.
In addition, some of the provided amenities left much to be desired. The heating unit in the apartment is just a bit old and (once fixed) made clanking sounds when it was on. It was also a bit hard to regulate the temperature in the apartment due to the analog thermostat. The towels that were provided were on the cheaper side (like $3 "room essential" towels from Target) and had stains on them. I mean, when you charge $3,600 a month, I feel like you could take it up a notch and splurge on the $9 towels. I chose to go out an buy myself better towels. The sheets too have seen better days, and had holes in them. I should note that everything was very clearly washed before my arrival, just old and of low quality. That's all.
Finally, on most evenings, a neighbor (not sure from which apartment) would usually smoke weed and the smell would flood the apartment. Just something to be aware of if that bothers you.
Overall, I should stress again, this isn't a bad choice for a long-term stay and I had a decent time at the apartment. Just pointing out some things for the consideration of future guests.
