We stayed for two nights in June 2004. The host is a very interesting man -- he's travelled all over the world, has collected many interesting artifacts, and tells good stories -- but his home needs a lot of work to be a good B&B stay, both for maintenance (the ceiling was cracked in places, with small bits of plaster falling down) and cleaning (musty smell, dirty floors).
The rooms were comfortable but not special, and the continental breakfast (bagels, fruit, juice & coffee) was okay.
Our overall experience was poor. We were glad to have a place to stay in a nice neighborhood in Chicago but would not go back or recommend it to our friends.
