1. All calls within the hotels are free. 2. Deposit in the hotel Khalidiya Palace - 100 USD per room per night. If you do not want to make it in cash or by card, you can ask to completely release the mini-bar when you check in, disconnect the phone in the room, leave a passport in your deposit and put a note in the hotel system to your Cash Basis number. But then you will not be able to write down anything on the room number and you will always have to carry cash.

The question of the deposit is settled upon check-in, everything is at the discretion of the hotel. When settling with cards remove / block the deposit, give a receipt, tourists sign it (Deposit statement). When evicting guests give a printout of the funds actually spent from the deposit, also signed by tourists. The default is to give a joint account, you can request a detailed one.
