We stayed 5 nights in this place. We are a little bit balanced :
The flat is very comfy, newly and very well renovated, very clean... almost every thing you can expect for such a stay and feel like home.
John and his wife are very nice and willing to help too.
On the other hand, it is a quite noisy place (1 room is facing the 9th avenue, and the AC - very good to have AC 😀- engine is keeping the window open), so you really need some time to fall asleep, or can be awaken hardly by a police car, or a truck... not very convenient if you are a “light” sleeper. It was ok for me, less for my wife to be honest.
Then, we were probably not so lucky, as a group of 4-6 homeless guys (and taking drugs) have decided to stay every night in front of the door of the building. Even if they were not violent, when you are with kids and wife, this obviously gives some “unsecured” feeling....but nothing happened, so just live with it...
Overall, this was a very good stay, and we enjoyed our week in the city.
