Dear Mr. Jaka, Sincerely, Monolux Solo Hotel. Thank you for your review of Monolux Solo Hotel. For your information, we use a card access system for the elevators for the security of all guests. For your convenience, we offer cardless access on the ground floor. If you require elevator access, we can assist you through our front desk staff or housekeeping staff in the lobby. Alternatively, a 50,000 Rupiah deposit is required for a spare key, which will be refunded upon check-out and after the room key is returned. We hope this information is helpful for you, Mr. Jaka, when you return to Monolux Solo Hotel again. Thank you again and we are glad you enjoyed your stay. We look forward to seeing you again soon. We wish you good health and happiness. Sincerely, Monolux Solo Hotel
