I stayed in Tammy's apartment for a week in February 2019. Here is what you need to know:
Tammy is a lovely host, she answers quickly, she is nice, she even left us water and snacks as a welcome and a local guide with maps and important transport music and food information!
As for the appartment if you are or if you are travelling with a very tall or big person I gotta tell you I don't think you are going to fit or be comfortable in the bathroom.
The living room and bedroom are quite big in comparison. Maybe small bathrooms are a New York thing, I don't know.
I am 5 feet and when I sat in the toilet my knees were only inches away from the wall. Also the bath tub was kinda small as well. I did feel like I didn't have much room to move freely.
The appartment is quite cold, but she did have a heater in the bathroom as well as two air conditioners with heating system, which was great!!!
The neighborhood is Harlem, I gotta tell you first day we didn't like it so much and It did seem kinda unsafe. But locals say Harlem is much more safe now than in the past. It is in a nice part of it near subway stations as well as the Apolo theater. And we didn't have ANY problems, everyone minds their own business. So in the end I ended up liking Harlem.
As for transport the subways we used the most were only four and seven blocks away! they are quite near yes. We used mostly our metrocard to move around the city, but when we ended up late at night, even thought the subway is a 24 hour service we rathered spend some money and call an uber, just to be safe, just in case. Which is what we are used to do back home as well.
We also liked that there was a supermarket right at the end of the street, just meters away from the apartment! That was so comfortable and dining in sometimes did let us save some money, New York is quite expensive after all.
I think this is it, hope this was usefull information.
If you don't mind about the small bathroom, I think you are going to like Tammy's appartment and have a great time just like my best friend and I had.
