I am a frequent AirBnB'er and Martin's place is "as advertised". It's a great house and he is a great host.
In my experience many hosts, perhaps understandably, oversell their place a bit. But Martin's was as he described it in AirBnB - which is to say "great" - it is a very stylish, comfortable house. In fact, we were tempted to stay in a little more than usual during this vacation trip to New York. With so many great reasons to get out in the city, and with most houses being small and not that nice, it was a surprise to us to sometimes find ourselves just wanting to stay "home" and enjoy the comforts of Martin's steam sauna (in Master bathroom), hot tub (outside on the third floor deck), garden area with grill (outside in a tree shaded backyard deck on the second floor), library and sitting room (second floor) or fixing a meal in his luxury kitchen (first floor, with all the tools necessary to pull off almost any meal). We had Wholefoods (Amazon) deliver a bunch of groceries and we were all set.
The house has four bedrooms - all nicely appointed - three of which have queen size beds and one (the master) which has a king size bed.
The house has a music system that you can control through an app (that my 19 year old mastered in about 90 seconds).
The street is quiet and we found street parking for our car a few feet from the front door. Maybe we got unusually lucky, but that was convenient (and free) on weekends.
The house has many stairs. Your come in through a front gate, then through a front door and then climb about 17 stairs to reach the first floor of the house. (All of my references above and below to floors refer to the house's internal floors - first floor, second floor, etc. - these floor references are based off the first floor of the living area of the house - (when I write "first floor" I mean one floor above the street level where you entered the building). You then have about 17 stairs between each floor (which is how you get all those nice, high ceilings). So the trip from the light-filled living room (with 30" ceilings and equally tall windows) to the master bedroom is 18 steps to the second floor (library, plus two bedrooms) then another 17 steps to the third floor. There is a final set of steps of about 17 stairs to the top floor - where you'll find another bedroom and outdoor seating area with picnic table. Our group of 6 (ages 19 - 56) did not have any trouble with the stairs, but my wife mentioned them once or twice as a being a bit of work).
Outside you are about 1/2 a block from Thompson Park, the same distance from a Catholic church, and about 2 blocks from a bunch of restaurants.
If you have any questions about the place just ask Martin. That's what I did and he always got right back to me with an answer.
