We didn't have the pleasure to meet Jennifer but she was very nice when we called her on the first day because we had some trouble finding the apartment. During the 9 nights we saw Geoffrey only 2 times but he was very nice and gave us great tips and adresses.
Concerning the apartment, the location is great and the room fits two people, but the cleanliness was a desaster and the door in the bathroom didn't close so we didn't have so much privacy which is not cool when you share your apartment.
