Don't stay here and don't provide your passport as security! They invent room damage and ask for a ridiculous $ to pay for it, and try to hold your ID to extort it.
We stayed at Shipwrecked Pension 4 nights in April 2017, and thought it was an OK place despite the cockroaches and what sounded like rats in the attic (look up other reviews on that) - not the nicest place we stayed but the town was packed. That is, until our last night there when they tried to scam us for made up damage.
The owner claimed we stained the bed with blood on our 1st night there (3 days earlier, and no one said a word about it before), that the mattress protector was ruined in the laundry as a result, and we have to pay 3,500p (ridiculous inflated cost for such a basic item, which I also know from personal experience is easy to clean). She had pictures of blood stained sheets which could have been from any time, and didn't show us the actual damaged items. We never saw any blood on the sheets, or on any of our own things, and surely would have noticed such significant bleeding as was in the picture. We discussed it with her at length that night and refused to pay as we did not cause any damage. The next morning at checkout they refused to return my ID unless we pay. Fortunately I only gave an almost expired ID as security, not my passport. So we just left it behind and walked away. We had to catch a bus otherwise we would have gone to the police.
