Marv is really great host. I recommend him without any doubt.
He is very helpful to find anything interesting in Chicago. A lot of informations/recommendations and ideas - what-to-do.
There was no problem with garage or late check-out (what was really great!)
What is very important - he left us his number in case we want to contact with him.
His "condo" is clean, well equipped and comfortable. Very good internet connection. Fully equipped kitchen. By this I mean also coffee (3 different types), tea and even a cold coke, water and everything what we need for our first breakfast. What a surprise!
Last but not least: location, location, location...
METRO is just around the corner (lest then 2 minutes), many grocery shops near by. A lot of restaurants and fastfood.
Neighborhood was friendly and quiet (as it could be in a center of the city).
In summary: next time in Chicago? Booked with Marv.
