5. The low rating is due to the blood stains on our sheets; a cup full of old, wet cigarrette butts on the balcony; bad reception on the flat screen; other guests` second-hand smoke wafting from their balconies into our room (all tower rooms are technically non-smoking, so smokers use their balconies); and very weak air-conditioning (which we tried to use once we closed the windows to avoid the cigarette smoke).
