I had a visit to pondicherry during christmas time. Booked the hotel in advance. No issue in reaching hotel as it is on prime location. There is ample parking space so you will not have that issue. There is not many choice for room so you have to decide based on your budget. Booked the delux room and it was pretty clean and well managed. Wi-fi was available so you can use it for free. Room service was pretty decent. Ac and geyser are good and worked well.
It has Pure vegeterian restaru so if you are non-veg then you have to eat out.
Overall a satisfactory place to stay and value for money. One plus point was the rock beach, french colony and churches are near by walakable distance and so the food point.
