We had no problems checking in or out, the house was very clean and comfortable, and while the location is not exactly central, it is close to the bus line and a block away from a grocery store. We were there for a conference. You can get to the convention center in 20 min by bus or 30-40 min walking.
Communication was easy. When I needed to contact the host, Ana responded promptly and came over to check on a leak in the basement, which didn't affect us other than the dripping sound for the person sleeping there. Also I forgot an item in the house, and Ana graciously let me come back for it one day after my stay ended.
