We had a great stay at Caroline's place. The basement separated unit made it extremely comfortable for my sister to have her own space with her baby. The hidden bookcase pass-through is super clever, though the openings are a bit narrow which could make it difficult to move large suitcases through to the space. Everything else felt super comfortable and clean. The location was great, super close to a lot of coffee shops and restaurants. Would highly recommend it when staying in Chicago.
