A lovely space in a great location -- a short walk to the Irving Park station on the CTA's Brown Line, and street parking out front is easy to find (though I should note that I was there when the Cubs weren't in town -- I don't know if availability might change when they are). Karen is responsive to her guests' needs -- she was even able to loan an old MacBook charging cable, which my friend had forgotten to pack.
The space is clean and inviting, and well appointed. My *only* quibble is that the toilet is pretty tight against the wall (this is something I've run into in multiple places before -- builders really need to figure out that this is not a good idea, especially for larger people like myself, but this house probably goes back to a time when people were mostly smaller ... still, be aware).
The kitchen is well equipped and was made ready for us, with a bowl of clementine oranges on the island, and water chilled and waiting for us in the refrigerator. Despite being an older house, the kitchen and its appliances are newer, and the rest of the space seems recently updated. There are plenty of books and DVDs waiting to provide distraction, and plenty of places to sit and relax.
We are glad we chose to stay here and would do so again.
