yes - stayed there. Can recommend. 6 or 8Euros. don't recall.
Special place (to me) - Did also enjoy the tour of the church and monastery (the only church in portugal -as we were told - that does not feature a cross - but the statue of Rainha Santa Isabel -. and the largest still existing baroque monastery. (still quoting the good guide we had ;-)
Monastery has great views across the river toward Coimbra. (and easy walk)
