Hmm, I think price is still fine.
never been con's earlier so cant compare for those, but 350€ and Ill get con fee + room for 6? nights (shared tho.) and hotel seems to be ok quality.
At finland small room at small town cost easily 500€ for 2 persons & 2 night, whiskey glass in same hotel 9€ and beer 6,50€
Tho, some "1 star" hotel would fit for me as well, never would know what you find in your room in those
