Flat for rent - Prague 1 - Nove Mesto

Four days before my roommates and I's arrival date we were told by the owner that she "double booked" & we would have to find other accommodations during the first two days of our arrival. I did not feel as if the owner felt bad about this mistake and when I asked if she had any places she would recommend to stay we were sent a link to a hotel that was longer open. We are three girls in our twenties that are traveling all the way from the states. Rather than canceling our stay (for the 3 months that we were planning on staying there) last minute, we found other accommodations these two nights as we were asked. Once we arrived we did not receive any help carrying our luggage/bags up the flight of stairs. When we arrived it was very humid and hot outside, my roommates and I were wearing shorts and a tank top and when we asked about air conditioning we were told that we could not have the remote. After having to convince the landlord to allow us to let us use it because it was stated as a feature of the flat on the listing. We were later messaged by the owner that she would pick up the remote not even a week later when it was still hot and humid outside. We were suppose to be refunded for the two days that we did not stay there but were told that the funds would now act as a "deposit" for the keys. This was never talked about until we arrived at the accommodations. We realized there were no paper towels, towels, trash bags, basic necessity items so we had to go to a market after first arriving to get these things. We asked for cleaning supplies, and only receive a mop that was falling apart/extremely dirty. We once again had to make a stop to the market to cleaning supplies to clean our flat.
Because of all these things, we decided that we wanted to put our 30 day notice in. The owner wrote me communicating that she saw this request but delayed the process by waiting to submit the inquiry with Flatio which delayed our depart date. We cleaned our flat for our check out date but it was not up to the owners standards so we communicated to we would pay her cleaning service 3 HOURS to clean it properly. Thinking that this would resolve the issue. I recieved a message from the owner about how unhappy she was with us and was sent photos of the apartment, including an image of the mop we were given to clean with. So we could at least agree that this mop was dirty - why was it given to us to clean the flat with? I was also told that a complaint would be made against to Flatio. Overall this was my worst experience in an accommodation while traveling. Not because the place wasn't clean, not because things didn't work correctly, but because the owner was so incredibly unpleasant to work with and I feel as if she look advantage of the fact that we were three young girls.
