That’s what sandbox is…congrats on negative test…must make sure you honor your entry requirements. Easy to ask front desk their expectations. Today my friends had tourist police in halls because someone tested positive and wouldn’t go to quarantine. So I thinks a sensitive issue - but for sure the front desk is the best way to win friends and do your sandbox properly.
Just make sure if they accept your low offer you are ready to close. It’s one thing to pay asking and take your time but if go way below asking they will lose face if you walk away.
Write hosts on AirBnB. They will have multiple places for rent (super hosts to start) and tell them your situation. They will let you book and then if you should have a problem will let you cancel.
