Punta Roquitos is located in Miraflores along the Costa Verde. It gets crowded early, but later in the morning it tends to thin out. I surfed out here for 3 of my days in Lima. I sat on the inside and caught a bunch of waves. It is pretty fickle as to the wave quality. Some were peelers into the inside with 200 yard rides. Others were a little wally with a quick bottom turn into an unmakeable section. The convenience of a spot really close to where I was staying made it worth it though. A swell started hitting on the day my brother left LA, so I was able to surf in some quality waves the next day.
