We stayed here because it had a decent write up in the Lonely Planet. However it was neither clean nor friendly. The room was filthy and the staff terrible. Our bathroom had muddy footprints all over it and when we turned on the tap, dirty water from the drain seeped across the bathroom floor. When we complained about this, all we got was one guy who took one look at it and said "no problem"! In addition, the toilet would not flush so we had to pour jugs of water down it.
Unfortunately there are very limited options for accomodation in Trichy. Hotels seem to dislike backpackers with many claiming they are "full". If you have to stop in Trichy, make it a one night stop!
