I have been living in MLC apartments in Midtown for 7 weeks now. We love the location! Great for people who want to enjoy being in the city, restaurants, bars, museums and art galleries and close to Piedmont Park at the same time. We had a couple of problems with the house and our maintenance requests were replied shortly. There was a crack in a window and they replaced it within a few days. The lock of one of the doors of the house was stuck. They replaced it right the day after I placed the maintenance request, within a few hours.
Their office is right on Monroe. The staff in the office is very nice and accessible as well. I would especially recommend it for graduate students!
