If you paid 700 EUR for that bed from Ikea, then you’ve paid a huge cost for delivery - no way is 700 EUR the ticket price. Which means you can’t claim it’s 700 EUR worth of quality.
The problem here is that you’ve drop fed and mixed up minor issues with major ones.
Not putting the rubbish out? I always do, but if you’re paying to rent including a cleaner - I get why some don’t.
Food in the fridge? I always want to leave it in case the cleaner wants it, hate the waste - but then feel like it’s just rubbish to them. I do chuck it, but I agonise each time! Again - I think it’s fine people see that as a cleaning job.
White pool cushions? Just a stupid choice.
Using the garden room? You just sound ridiculous saying they shouldn’t. They’ve rented the whole place. If 1 person rents a 5 bed place and CHOOSES the room by the pool - their choice.
Calling because they couldn’t use the hot water? They didn’t do that for fun! Your fault for not making it clear.
Pool pump - again, they didn’t call for fun. For whatever reason they thought it wasn’t working efficiently - if I had the slightest doubt I’d call, so I didn’t get blamed if it was fault after I left!
Broken tile and pulled wires - who knows? Sounds bad, but as so much of the other stuff YABU, I’m inclined to think you are on those, too.
Absolutely understand that people trash places - I had a non holiday rental absolutely trashed. Doors off, graffiti on walls...
But you’ve not really convinced me with your photos. And the bed definitely looks like cheap crap for a rental!
