Gisela worked with us before we arrived and accommodated our travel schedule (our flight got in at 5AM and she let us come in around 6:30 AM). She was very helpful when we first arrived and provided useful information about where to go and what to see as well as providing us with two subway cards (although we did not end up using them). The apartment was clean, had everything we needed (including a kitchen and living room), and was in a convenient part of town. I would definitely recommend staying with her!
