This was a terrible experience and the first time I have ever had to leave an Airbnb property after many years using Airbnb successfully. The flat was beautiful but the plumber explained because the building was largely uninhabited the plumbing didn't work properly and the flat smelled really badly of sewage making us gag and feel sick. We vacated the flat for the first day because the plumber told us we couldn't use the toilet facilities while the solutions he put in drains were taking effect. He explained he was not convinced the drain products would improve the situation but worth a try. When we returned late at night the smell was worse - even outside the flat at the lifts. We knew we could not stay in that environment that night and took refuge in the tiny apartment of friends. Despite cancelling the booking so early and LetMalaga's refund policy stating unused nights would be refunded they refused claiming the problem had been fixed ( it categorically was not fixed and was indeed worse). We had to involve Airbnb to resolve the issue which took days and spoiled much of the holiday.
