Kasauli Pebbles is a good place to spend a couple of nights while you explore Kasauli and its neighbouring areas. The room was very comfortable, clean and spacious. The service was prompt and the staff courteous.
I did not try out the restaurant as it serves only vegetarian food, and there are so many great food options in Kasauli town, which is about 2kms away.
In conclusion, Kasauli Pebbles is a convenient and comfortable place. Do not expect any frills, or any activity in the hotel, but it serves the purpose if you are looking for just a nice place to rest after a day of exploration.
