Karen was extremely helpful!! I had people over for a bridal shower and Karen had extra chairs and even offered to bring up an extra table. The location is extremely convenient if you have a car/ are renting a car as it is right off Lake Shore Drive. There are bus stops all around the building if you are using public transportation. The neighborhood and building are safe and quiet. The apartment is very large, homey, and has wonderful views that made me wish I had more time to stay. It was really like staying at a close relative's house. It was comfortable and had pretty much everything you could need, there was some coffee and condiments in the fridge, sightseeing info on the table, and some toiletries in the bathroom! Karen was flexible on check in time which was a big help so I didn't have to worry too much about when my flight got in early.
