I visited Pondicherry last week( 21st Sept till 28th Sept 2014), a good place to relax & unwind if you like the calm city. You have many places to see in and around, auro beach, gandhi beach, paradise beach, Auroville, Aurobindo Ashram, a temple, or you can just take a leisure walk in the evenings on beach road which is a very nice place.
We stayed in aurobindo ashram guest house which is perfect for a long stay. Liked the place, will visit again.There are many good food outlets A2B, Suruguru Residency & many cafes, only drawback is autos charging not less than 100 bucks for just few kms you go, !
