We stayed with 4 people in the "Sophia Room". We had our own bathroom, directly attached to the room, which was great. Towels, soap and shampoo etc was all provided! Space was very clean. As indicated on the posting, the house is located about a block away from a CTA stop, which makes going into town super-easy. Neighbourhood is also very safe. Two things to keep in mind when staying here:
1) when the couch is folded out to a queen bed, there is no space left in the room. There is a very narrow path (couple of inches) to the bathroom, but that is about it. We travelled with only hand luggage so we didn't need so much space, but it was definitely very packed.
2) if you are afraid of dogs, this is not the place for you. Owners do their very best to keep dogs in check but both dogs seemed wary of strangers in their house. We all grew up surrounded by dogs but we're uncomfortable with these at times.
