The appartment was not as it seemed in the advertisement, and the landlady was very, very rude.
I had informed her in advance that I would arrive with my parents who would stay with me for a few days. Through the messages, she didn't seem to disagree.
But, when we arrived she was quite surprised by their presence. Maybe it was because she doesn't really speak english and didn't understand my message. And of course, if there is good will, language is a problem that can be managed. But there was not.
She was an hour late for the check-in. We were given the key by another person, but still she was the landlady, so we had to wait for her, since there were a few problems in the house. It felted like they were not expecting us.
She had claimed that the appartment was first floor, and it was ground floor with a window on the street with rather transparent curtains. It was quite cold also.There was no cooking pot, no soap, the towels seemed used, there was dirt in the bathroom, one unwashed dish, a big spider, two spider webs, no oven, I had to ask to bring me the microwave oven ,the clothes washing machine was in the common hall, shared with 2 more appartments (something that is not specified). On top of that, she was quite un-eager to help. She brought additional heating (the same night at 23:00 when we were sleeping) ,new towels, soap, shampoo etc (after 2 days or something) but she was aggressive and rude, when I was just asking for what she had claimed to be included in the advertisement. I can refer many other cases in which she was rude, like when she came knocking my door at 9:00 on a Saturday morning, before letting me know in advance, to show the place to the new cleaning lady, but it would take too long.
When I asked if two relatives who wanted to visit me could stay with me she unswered that they should rent a hotel and that she already had made an exception for me by letting my parents stay free of charge. I sent her a message saying that I respect her will. Some days later, I received a notification that she has terminated the contract and I should move out in a 30 days period.
Luckily enough, In just one week I had already found multiple other choices for accommodation, better and cheaper.
I moved out before the notification period,and although I repeatedly asked her to make our move out date formal through flatio (I even had a friend tell her that in czech and she said she would), she did not, so I had to pay for the remaining days of my contract without really living in the flat, thanks to the quite unclear flatio contract that doesn't really protect tenants. I had also asked her to bring the handover protocol for signing, but she did not.
I am happy that I moved out anyway and I am not living in this mess anymore.
