Sector 15 Part 1 is generally the quieter half of Sector 15 — dominated by builder floors and older, settled residential streets, sitting closer to Civil Lines than to Sector 15's busier market side (Part 2).
Star Stayz Sector 15 residents in this part of the sector get a calmer, more residential feel day to day, while still being a short ride from Old Gurgaon's markets and the rest of central Gurugram whenever they need it.
If you're the kind of resident — student or working professional — who wants a quieter street to come home to after a long day, this half of Sector 15 tends to suit that better than the market side.
