Nothing.

If you want a horrible hotel experience then book a room at Urartu Hotel. Two reasons: 1) This is a small hotel, surrounded by several restaurants with life music, which produces noise untill 12 am. They don't care about your rest, they have birthdays and wedding outside to serve. Period. 2) The don't care about you privacy. I had fully armed security 6 men in my room at 4 am!!! What happened? I had 2 friends who visited me that night and hotel's manager said there could not be more than 2 person in a room. Therefore they called fully armed 6 security men at 4 am to get my 2 friends out. I replied them to show me the rules that I can't have guests in my room and they had none rules to show me. Avoid this hotel at any cost!!!
