Flights To Magaluf Can I Use An Apartment On Holiday That My Mates Paid For?

Can I use an apartment on holiday that my mates paid for? - flights to magaluf

Sorry, I do not know a word of the title.

Paid Basically, a group of colleagues for flights and accommodation in Magaluf on the holiday and has asked me to join, only pay for my flight, "she said in one of its rooms to stay.

Is this all illegal? And / or what you can do the hotel, however, if they surprise us?

Thanks
