The room has an incredible memory foam bed, which made sleep very easy. I never saw the other guests in the house except a couple times. They didn't cause me any trouble with bathroom but that won't always be the case. The room is warm in the winter but bring some layers for the rest of the house.
I didn't actually meet Natasha, just her brother and sister. They were both very accommodating and nice. They seem to live in the basement so they can be available most any time you need something. The area isn't 'bad' as some others said previously. It just isn't good. My suggestion is look up the event history in prospect park on this side and you decide yourself before going.
It is a bit of a pain to get home late. By late i mean after 9pm on the weekdays and 11pm on the weekend. One train. Often delays. Usually took be twice as long as expected. Just know that and learn the bus routes too.
The park is beautiful. Go for a walk during the day. I walked instead of taking the train often during the day and it is a great walk to many of the best things in Brooklyn.
