In Marisa's castle you will have an entire floor for you. You will share the entrance with the family, but than the apartment is located on the third floor and is entirely separated. The apartment was clean; perfect check-in and check-out. 15 minutes walking distance from Flushing Metro station, line 7, that takes you to Manhattan in about 30 mins. You can also take the Amtrack train but it's much more expensive. We spent three nights at Marisa's place and easily reached Manhattan every day. The neighborhood was quiet and we never had any trouble walking home late in the evening. Flushing is mainly Chinese, there are lots of shops. We didn't have time to explore the area but it's surely interesting.
We had a relevant problem during the first night due to the malfunctioning of the old stove. Marisa and his daughter have been willing to resolve the problem quickly, called a handyman even later in the night, and provide us with a camping stove the day after. We really appreciate that they immediately took care of the problem. Overall a good experience!
