I had a fantastic experience at Marv's place! The apartment is cozy and quite spacious, and comes with a fully equipped kitchen and a reliable Internet access. The bedroom features a comfortable bed. Keep in mind though the bedroom can be a little noisy as it faces Wells St. It can be a busy area, even at night or early in the morning.
The building features a laundry room, which turned out to be much useful during my stay.
The location of the condo is pretty convenient, being very close to the 'L' station at Clark and Division. Red Line trains will take you to the Loop in a few minutes. The beaches can also be reached easily by foot and south of Lincoln Park is at walking distance too (no more than a 20-minute walk away). You'll find lots of stores (including the excellent Plum Market) in the neighborhood, as well as nice restaurants. You can enjoy a good American breakfast at HashBrowns, a cafe literally right next door.
Marv himself was truly a great host, very easy to communicate with, whether through texts or on AirBnB. It was a pleasure meeting him in person.
All in all, I would highly recommend to stay at Marv's place!
