The airport is 1 hour away from the city. If its your first time in the city, best way to get to the city is using UBER or OLA (an alternate app to UBER)
Best way to travel within the city is also through the same apps, try booking an AUTO for short distances and to have a full local experience around the city :)
Vinay’s and Sanjana’s house is 500m away from each other, so your stay can be close to either :)
