We usually travel Mumbai-Pune with MSRTC, but on one day we needed leave early from Pune and therefore opted for Neeta, Mercedes - Benz. The only good thing was that in spite of the fact that ours was not the first stop of the bus, we cud get the front seats. But the bus waited for almost 30mins as there was some issue (loud quarreling) going on with the earlier bus passengers (as it had broken down).
We therefore lost time there. After which the bus started but the driver and his navigator were constantly talking amongst themselves, which left us were wondering if the driver is actually paying any attention on the road. Moreover the driver was also answering and making innumerable phone calls during the drive! They also forgot one passenger at the Lonavala stop, whose luggage was to be sent back.
The seats were very uncomfortable and the AC was too cold (in spite of requesting several times to the navigator!)
Also, if you negotiate with them they will also reduce the price of the ticket from 300 to 200. You should just let them know that you have time and can opt for other travels!
Compared to this, MSRTC which is government is way much better!
