My 3 friends and I stayed at Johny's place for one full week and had an amazing time!
Of course Manhattan was our first choice, but if you're looking for something much much much more affordable, Brooklyn would be the next best thing. The Myrtle-Willoughby subway station is a quick (and safe) 5-7 min walk away. We went into Manhattan every single day and it was about a 30-40 min commute, which is not bad at all.
My only gripe is that the walls are a bit thin. I would suggest bringing some earplugs if noise levels might be an issue for you.
But other than that, I would definitely recommend staying here! His place is spacious and comfortable. Johny really lives up to his superhost badge. He was always prompt at replying, extremely accommodating, and super friendly!!!
