This place was very clean and nice, with a good bathroom and comfortable bed. We recommend staying here if you are near Mahidol university. It is only 3 kilometers down the road from the campus. There is a 7-11 across the street, and also good food nearby.
The Sala Ya train station is only 4 kilometers down the road, so it is easy to get a train back to Bangkok or down south to Hua Hin or elsewhere.
The only problem was that there were often times with no staff around, so we had trouble getting service or questions answered quickly.
