Museum Boutique-Hotel in Belgrade

I don't think I will come to this hotel in the future, nor will I recommend it to my friends.
First, the room is very small. This is a facility problem, which can be ignored, but the room is very hot. The air conditioner is set at 24 degrees. It should be fine at 24 degrees, but the room is very hot. If you want to adjust the temperature down, it is impossible because guests cannot adjust the temperature in their own rooms. We found the front desk and the waiter and adjusted it to 19 degrees. It was freezing at night, so we wanted to adjust the temperature. It was 24 degrees, and the room was hot again in a short while. The room was originally very small, and it was very hot in a short while. It was strange that guests could not control the air conditioner in their own rooms.
Second, the hotel did not say that any food and drinks were not allowed when checking in. After we checked in on the first day, we went out to eat and went back to the hotel without finishing the wine. The weather was okay at the time, so we sat at a small table outside the hotel to drink and chat. We took the half-can of beer in our hands back to the room without finishing the drink, and no one said anything. We also didn't know that the hotel would have a system that prohibits bringing drinks back to the room. The next day we were drinking beer and planning to sit at a small table outside the hotel, but we found that there was no small table. We thought we could sit at the hotel reception desk and chat for a while because the room was too small. The receptionist came over and said that we couldn’t drink our own beer here because it was a bar. There was alcohol for sale. We said we only had this can of beer, and we would go back to the room after drinking it and chat for a while. The receptionist said no. We said we would go back to the room to drink, but the receptionist replied that it was not possible because the hotel does not allow any outside drinks and food. I said we sat outside yesterday and you had a small table, but not today. The receptionist said it was because it was raining. We said it was raining yesterday, too, and we sat at the small table and watched the rain. The receptionist meant that we couldn’t drink here, but we could buy it. We couldn’t take it back to the room. We said we saw a foreigner bring food in yesterday, but you didn’t care. And you didn’t tell us yesterday when we took a half-finished can of beer, not to mention that we didn’t tell us this rule when we checked in at the front desk. This rule was not written in our Ctrip reservation. The receptionist meant that we had to go out. Whether you are a guest or not, or you threw away the wine, you can buy wine in the bar of this hotel.
This bullying attitude, the attitude of forced buying and selling, is determined to make it impossible for people to consume in your hotel. If you had made it clear when checking in, and informed the guests that if we violated the rules, it would be our fault, then we would admit it, but you want to treat guests this way today, and treat guests that way tomorrow, one day at a time. You are nicer to foreigners and are accommodating. You start to kick out Chinese people. It's a bit too immoral. Who dares to stay in your hotel in the future?
I thought Serbia and China have a friendly relationship, and I thought you would welcome Chinese guests, but you treat them differently. And this arrogant attitude. Too unfriendly.
