Seems like it would be enough. I know most of the apartments I've lived in were under 1,000 ft^2 and I shared it with a roommate.
If you have a lot of stuff or need space for a home office, guest room, etc. that may push your needs up but otherwise it sounds like a generous size for one person.
It's more than enough for a single person. I'd suggest you move an extra body in, preferably a lady friend ^^
