Can 17 year olds stay in a hotel or appartment in spain without an adult?

Me + my mate want to go on hoilday there this summer, if you can go on hoilday when ur 16 does that mean u can stay in a hotel?

When registering at ANY hotel you WILL be asked to present positive identification...a passport or EU id card. To avoid great inconvenience and an unexpected refusal, I would definitely check with your expected host. 17 years old is still a minor in Spain. You could be refused simply because of the hotel's insurance liabilities.

for sure

yea. but you need an adult to make the reservations

yes but you need and adult over 18????? to make the reservations. I don't know why
