We found the keys, but then saw the external spiral staircase may be dangerous as (unlike others) it had no handrail. We knew there was no lift, but my wife’s disabilities mean she can’t use stairs without a rail. The stairs could be wet & slippery from rain or someone using them after being in the pool. Risky, especially for elderly & children.Phoning elicited no response so I emailed. Up at 4am for an early flight we needed rest so booked a night in a hotel, hoping the Host would respond.A few hours later they got in touch. I had already mentioned my wife had disabilities. We could not stay at that property but my request for a substantial refund was rejected. As they hadn’t offered any solution by next morning, I paid the hotel for the rest of our trip (1,000 holiday cost increase). Too late, the Host then offered other properties.We agreed a 50% refund of the rental cost. I was assured I wouldn’t pay the cleaning fee. Next day the Host reneged; I must pay for cleaning a property we hadn’t used.I was pressured to sign a contract to say I was content and should not seek any further costs. I signed to reduce my costs and try to enjoy the remaining few days in Denia.Spain recognises the risks and requires handrails on stairways, with some exemption for properties built prior to the regulations. A business that lets properties, should have a duty of care to guests. Not only has the Host used the exemption, but the absence of a handrail was not mentioned in the listing.
