Is this just NYC or are my concerns warranted?

Hey all! I just moved to Manhattan a month ago chasing a job in hopes of a better career, though I’m dealing with some apartment concerns and was wondering if this is just how NYC operates.

I moved into a new construction spot, 15 units, up in Harlem. I found out the day I moved in that I was the first and only tenant. Didn’t think too much of it though now I’m wondering if there’s more of a reason why. I hear from locals that the building sat vacant for a long time and most seem surprised the building is now finally being occupied.

I’m a month into my lease and I still don’t have a buzz-in system or mailbox. Making it difficult to get items needed to fully settle in. All the equipment is in place, it just all needs to be hooked up. I’ve been told since the beginning of the month that my super is waiting on management or that they are working on it. I was able to find my management company online, and the reviews are horrid, adding to my concern.

Separate issue is that my oven is getting no power since I’ve moved in and my super has scheduled to come fix it and then cancelled each of the 3 times he told me he would be coming. As of this morning, he let me know that management wants to send a tech instead, though I only found this out after reaching out to him an hour after he told me he’d be coming for the 4th time. My super is super responsive and genuinely seems to want to help, but may be constrained by management, or perhaps they both are simply not reliable.

This is my first time apartment living as I’ve lived only with family up until this point so I’m unsure if the flakiness and slow to act experience I’m having is normal for NYC or apartment living in general?

What do you all think? Thank you for any tips or guidance in advance!

Edit: I wanted to add some details, I have confirmed the building has an Occupancy Certificate. Also, there are mailboxes for each unit, though I’ve been told by the super that he needs to register them with USPS and that it’s taking a while. Thank you everybody for all your comments!
