A friend and I stayed at Aum Homespace for just under a week in our trip to NYC, and the interior (bedroom, bathroom) was very nice. We did encounter an issue with getting the keys during check-in and weren't able to reach Vanessa immediately as she was out of the country, but it was sorted out within half an hour by her sister who was extremely helpful with managing the space. We also knew we would be sharing a space with the host but not that there was another room being rented out - this wasn't an issue and we didn't bump into each other, but additional notice would have been nice.
Do note this is an old building, so we had an issue the first night with the heater making loud noises every two hours and the hot water not running one of the mornings. However, these were fixed within a day. The location also may not be very central, but it's an easy subway away, and although we were initially a bit concerned about safety, it turned out completely fine.
For the value, this was overall a great stay.
