Stayed there for one night before going to visit the ruins.
Really convenient place (15 min walk to the ruins), they opened a room for us to have access to bathroom and shower.
We were charged 120L for two people in a campervan.
The ruins (not including museum and tunnels) cost 15$ / 345L per person.
