I stayed with Luisa and her son Rolando for 6 weeks during an internship.
They are both amazing and genuinely nice people, who helped me a lot finding my way around New York.
The room is just as advertised, very comfortable and a great size for New York. There is enough closet and dresser space for two full suitcases of clothes and the bed is super comfortable, I got many great nights of sleep. It's great to have your own fridge with a freezer in the room, the kitchen is well-equipped too and I cooked for Luisa and she also cooked some amazing dinners for me my first days. The bathroom is tiny but clean and functional.
This place is ideal if you are looking for an affordable, safe and homey place while staying in New York, although it does take about an hour on the Subway to get to Midtown/Downtown. But the connections to bus/train stations are great, you have the option between the 1 and the 4 train, both are within walking distance, but there are also busses going to both stations.
I would definitely stay here again and highly recommend Luisa's place!
