Monica is super nice and the location is around a 4-5 minute walk to a train stop. We specifically used Myrtle Ave so it was super convenient.
It is in Brooklyn and there are a lot of bodegas and shops that you can get fresh produce at.
Because you have to cross the road and it can get quite busy near traffic hours, just watch your surrounding.
As usual with anywhere, I would avoid traveling alone late at night.
COVID safety wise, we didn’t worry if the place was clean or not because it looked spotless upon arrival. For NYC itself, I still would recommend bringing masks and have ample hand sanitizer available because traveling in public transportation will always be a higher risk vs. more open areas.
