You can enroll for a period and then decide to extend your stay as long as you want. Just note that the longer the period you enroll for, the less you pay, because after the 5th week there is a special price. If you extend week by week, you end up paying the normal price, which is more expensive than enrolling for a 5-week period or longer. Another thing is that your room may not be available at the end of your first period, requiring a move. Yes, the 3-star hotel has all of these facilities included in the price.
Breakfast is included too.
The 3 star-hotel has a good cleaning service and good extermination practices, too. The hotel has 24-hour security. To bring additional guests to your room, you have to pay an extra fee and deposit the guest s identification at the reception desk. The guest is not able to leave the hotel without your permission. Of course you can do what you want with your free time.
