Hi, I wander if, in order to complete the quarantine period, I should book a specific Hotel/Apartment or if I can book any Hotel. Thank you.
I believe your company needs to provide a plan so as to your activities immediately after you land. That includes a place to stay during quarantine.
It depends if you are a business traveller, a returnee, or a new entrant under a student or trainee visa. As @justaguest says, there are strict requirements on the company that is hosting you as a business traveller. If you are entering as a returnee, you have more flexibility. If the hotel or vacation rental apartment will accept your booking, you can quarantine there. Most hotels are quite accustomed to it by now, but the higher end places are more receptive than the cheap business hotels.
