It seems this building is one of I assume a nationwide chain of serviced corporate apartments. As that market is likely decreasing, they seem to be branching off to Air bnb.
We were back in NYC visiting having lived her for many years, and picked this spot primarily because it was around the corner from our old apartment. So the nostalgia factor was high, but FiDI IS a great neighborhood.
We had a couple of minor issues (not enough towels, something broke) and the response time was super fast.
It was tiny and bit pricey even for NY but it wasnt too hard to remake the couch each morning and was perfect for our needs. I even managed to use the convection oven to successfully cook a pumpkin pie- kitchen was well stocked with measuring cups and spoons, etc.
