Hi, welcome to Just Answer. I will help you with your question.
Is the theft linked in any way to the building works?
And did you purchase this as part of a package, i.e. with flights and/or with transport to the site etc?
Okay, so this was really just the let of the apartment then?
okay. Did they describe the apartment as being "quiet" or anything like that, implying no building works?
Okay - then you might have a claim for breach of contract, in that it was something that it was not described to be due to the building works.
You would be able to claim for loss of enjoyment during your stay.
This is a difficult thing to put a precise figure on, as every claim is different and the courts have a massive discretion on this. There is no legal precedent as such as every case must by definition be different.
That said, it might be something in the order of £500 or so. The damages for this type of things tend to be low in our legal system.
You would make a claim against the person your contract is with. Most likely, this would be the owners (if this was a company that lets out for lots of different owners), but you should check any written document that you have on this.
As for the stolen ipad, you're almost certainly going to have to claim on the insurance for this one.
Does this answer your question, can I assist further?
Fabulous - good luck in resolve this. If you need me in the future, just let me know.
