First time using the app to unlock the doors to the apartment, elevator and apartment. It was pretty convenient. The location was great for me. Wasn't far from McCormick center or any of the places we went to dinner which was northwest of us. I took an uber everywhere. The did notice that the L train stop a block from the apartment is only for people who already a loaded L card or else you need to walk up two blocks north. The area around the air conditioner was falling apart so I let them know. They were great in communicating and responded very quickly.
