The place seemed clean and had most of the things I needed

Everything was okay except that it was a little hard to communicate with the house owner as she speaks Ukrainian only and the Wi-Fi range was not reaching my room and the house owner told me that she can't do anything about it, also the area seemed to be far from the city center and I didn't find any nearby shops or anything. However the main thing that made the experience terrible is that the house owner agreed to keep a bag in the basement the day before I leave as I was heading to another city and moving with three bags would've been struggling, then the day after a few minutes before I leave she told me that she can't keep the bag for more than 1 or 2 hours, and it would not have been a good option to book a room in another hotel at the same day because I booked a room already in another city. I tried to negotiate with her so hopefully she could be a little bit understanding because she already gave me her word and I made up my mind and arranged everything so I could leave the bag with her but refused to do anything further and yelled in Ukrainian and turned her back on me and left saying "Write me". I kept moving things from one bag to another and tried to call some people to hopefully find a connection or something to leave to bags with and before I was done she called the customer service and complained about me and when I explained what happened to them and asked them for a few minutes and they were okay with that she seemed to be angry about this resolution and told me to leave or she'll call the police, she didn't have any kind of sympathy or humanity and didn't care that I'm alone with nobody in Warsaw, one if the hardest situations I faced, people should keep their words, if I had known I'd not have faced this.
