We stayed at Hotel Treebo Grace Inn for 3 nights (Oct 14-17, 2017) during a recent family trip to Pondicherry. I would recommend this hotel to tourists who primarily want to get away from the din of city life and relax with family. Being located within the White Town (i.e. old French Quarters), it is a walking distance from the Promenade beach, the Aurobindo Ashram, the marketplace as well as several excellent restaurants. With the discount offered by Expedia, we found it an economic and decent stay option within the White Town.
The staff are friendly and accommodating. To cite an example - on one occasion, the toddlers accompanying us created noise in the corridors late in the evening and some other guests complained at the reception. The staff in charge was courteous almost to the point of apologizing while informing us of the complaint. While it is hard to restrict toddlers from running around, we did our bit to help the situation in the following days.
Another important point is the ease of cancelling prepaid bookings which entails full refund within 3-4 days if done within the free cancellation period. Also, one of the families accompanying us on the trip asked for a late checkout (around 7:45 PM) and it entailed half a night's cost - which we found acceptable.
