The issue was not the apartment which was nice,clean and well located. What was annoying was the additional rules not mentioned on the site. The agent told us that if we drank the cokes or beer in the fridge we would be charged a 1€ each. We asked whether or not the tap water was potable and the agent told us that it was but it tasted nasty and that was why bottled water was provided for us in the fridge.The agent also told us we could use the clothes washer and showed us the detergent tabs to us-no mention of cost. As well if we used the air conditioner, Emiliano did not want us to use it at night.During our stay we drank the bottled water and used 1 tab of detergent. We didn't use the air conditioner.A day after leaving, Emiliano made a claim to Airbnb for 4.50€ for our consumption of the bottled water and 1 tab of detergent. We declined the petty charge and explained our concerns to Airbnb who declined his claim. We have stayed at many Airbnbs where the hosts have left bottles of wine,juice,water etc free of costs.Hosts who provide consumables at a cost should outline these in their house rules on their Airbnb site. If an air conditioner is listed as a feature on the host's Airbnb site its use should not be restricted. This pettiness detracted from an otherwise pleasant stay.
