We stayed at Lillian's place for 9 days. We had a really good experience. The apartment is close to the subway and in a good location both for reaching Manhattan and for restaurants/shops in Astoria (not much noise during the night and a safe area).
We didn't have the chance to meet Lillian, but communicating with her was easy and she showed to be available all the time. The apartment is lovely and in good conditions, however there is no much space for your personal stuff and luggages since Lillian's belongings occupy the storage and most of the space in the rooms.
In general, it is a great place to stay when visiting New York City.
