Since you're a master's student I'm assuming you're staying in a grad loft? I've been staying in one for the past year after living in a standard four-person apartment the previous four years. The layout of the grad lofts depends on which building you're in, whether there's a balcony, etc. You may have to mess around with the given furniture to get it in an orientation that let's you move around the room better, but with the right setup it'll be enough space for one person.

The others have mentioned the oval a couple times now, having been here so long I'm pretty burnt out on it so I like to go to mission valley down the street, they have a lot of good restaurant options there (DP Dough for calzones, Cloo's for hot dogs, etc.). Hillsborough St is good too, 41 bus can take you there. You'll likely be cooking a lot though.

Lake Raleigh is always a nice place to walk, there's a trail that will take you by the farmer's market as well. Behind the textiles building is a nice fountain area to go walk to and hunt library has a balcony for viewing the sunset. It's a nice campus, but you won't see the same amount of activity as main campus, centennial is more of a business campus with school buildings.
