I stayed at Matthew’s for a 3 day weekend and then worked from there on Monday.
WiFi was excellent, did not need the Ethernet cable that I brought with me. I asked just before I went if I could borrow a monitor and Matthew provided one so I did not have to check in a luggage. Location is great, you can walk to Navy Pier and take the water taxi to museums, Sears tower and Millennium park. Locally you can walk to many shops and restaurants. Starbucks Reserve is a few blocks away and there is a Trader Joe’s I did go and get groceries.
You cannot go wrong with this place.
