Natalia's place is spacious, stylish and in an excellent location.
The apartment is on the second floor, with a large living room and a small office overlooking the street. The bedroom is toward the back, but still has some nice natural light — this is a dense neighborhood, so the building next door is close-by, but it never felt dark or intrusive. The large, well-equipped kitchen is in the far back, with an indoor porch area behind it. The apartment is on a busy street, but it was never noisy inside, and I had no problems sleeping soundly.
This is not your typical "we moved out all the nice furniture and replaced it with cheap Ikea shit" Airbnb! The furniture and fixtures are all really nice, things that I wish I had in my own home. It is also filled with thoughtful touches — lots of places to unpack in the bedroom and bathroom, 3 different kinds of coffee brewing equipment in the kitchen (plus a coffee grinder!), myriad charging cables conveniently available in the office, and a very detailed "guidebook" to the neighborhood on the dining table.
Natalia is definitely an involved and helpful host. The check-in instructions were clear and easy, and she checked in several times to make sure that everything was good. When the weather shifted abruptly from hot to cold, she made sure I knew how to adjust the thermostat. She even pre-stocked the place with some drinks and snacks and coffee beans.
I hadn't explored this corner of Logan Square before, but the neighborhood is great: there are some great restaurants right down the block (between dinner and morning pastries, I went to Cellar Door Provisions no less than 3 times in 5 days). It's also an easy 10-minute walk to the center of Logan Square, with all of the great restaurants, bars and stores there, and to the Logan Square Blue Line station, from which you can get just about anywhere in the city.
Overall, a great experience! I would definitely stay here again when I'm next in Chicago.
