Julian is a very nice guy. He is very responsive in the Aibnb messages and allowed us to check-in as soon as we arrived to NY. Julian came downstairs and welcomed us the following day, without a message noticing us about it, but he was very nice giving us tips for things to do in Queens.
I should say that reading other reviews I was a little worried for the noise and the people living upstairs but in our case, we did not have any of these problems. The whole flat was quiet after 12am (at the latest), and the noise you might hear before that is the typical steps (no shouting or anything else). Although, it is true that the fridge in the Airbnb is quite noisy.
The only problem we had during our stay was that the toilette clogged. However, we messaged Julian at 12am and he immediatelly replied and fixed it the next day when we were visiting NY.
The style of the Airbnb is exact as pictured. We really liked it. And he put natural white roses in the center of the table for us (which was a really nice touch). I should say I loved the kitchen wall! With the domino's pieces. Very original.
On the other hand, there is no truly separation between the basement (the Aibnb) and the upstairs floor, but Julian assured us that no-one would step into the Airbnb (and I should say we did not have any problem related to that).
