Heads up, I approach any review as if I'm writing it for myself. So if you're not an old millennial parent of young kids, you may want to skip ahead.
Overall, Erhan's place is exactly what it positions itself as: a decent place to lay your head for a decent price. Beds were comfy, plenty of glasses/utensils, strong and reliable wifi, place was clean enough, etc.
As far as location goes, it's a little on the outskirts of all the cool going ons of Roscoe Village, so don't expect to be a stones through from the neighborhood's well-known eats. That being said, having a dedicated parking spot with 24/7 in-out access is amazing for families, and is worth the trade off in terms of distance from cool things.
NOTE FOR PARENTS: Apparently, the floors are a bit thin between this space and downstairs. We'd only been in the apartment for 20m before the neighbor came upstairs and very strongly vocalized that we were being too loud and needed to keep it down ( I want to stress that he was respectful, but he was absolutely upset; it also felt like this is a regular thing for him to go upstairs and shoot a warning shot for all new guests). Anyone with a 2yo knows that they can't just calmly walk across a room — they have to skip/jump/twirl/whatever — and when ours did that, we were often met with a broom handled banging from below. When we travel, we use our airbnb/hotel as our decompression space: it's where we can relax completely, including our kids. Unfortunately for us, we were constantly on eggshells making sure our kids stayed quiet during our stay, which overall made the trip a lot less enjoyable. I feel like the neighbor situation is out of Erhan's control, but it's absolutely worth noting for families that are considering this space.
