We spent one night after 10days trek across Muntii Lotrului and Muntii Sureanu there. Very friendly hotel 5 minutes by walk from the center of town, very friendly personal. I think the price (120RON/1 doubleroom**) is equal to quality. We could choose between ** room and *** room - the only difference we found in equipment of bathroom - in 3* room there was more modern equipment, but both of them had bath and there was no problem with warm water. The second day we could left our big backpacks at the Reception and visit the town with our cameras only...
Near this hotel there is a typical romanian park with chess tables and some equipment for children - we could find there how Romanians spent their Sunday in the small town :-) Many shops and caffeterias in the center - but raise your head and look above - you will see the typical contrast between quite "luxury" shop on the first floor and old house above.
I can recommend to visit not only the main street of Petrosani but to find the hidden streets and places with romanian architecture. This contrast you can find in every town or city what you visit.
I recommend this hotel to everyone who wants to spend there one night only or stay there for longer period.More
