This is our experience and we want to make sure others don't fall into the same trap as we did. Maybe our guide was involved as he was the one who brought us straight there and we trusted him, unknowingly.
We did the Annapurna Sanctuary just 2 weeks ago and put up in Hotel Snowland as the airport in which our early morning flight was to be was just across the hotel. Upon payment of our bill, we were charged 1050nrp for a triple room with attached bathroom.
The highest we had paid at high camp was 500nrp.
We were the only guests at the hotel and we had ordered our food all at the hotel. It was too late to move out. We questioned the owner who ignored us and refused to do anything about the billing.
Jomson is accessible by many forms of public transport unlike the remote trek area in Manang. To be charged this rate is simply ridiculous!
Please avoid this hotel if you don't want to be fleeced. There are many much better ones just close by and much cheaper.
