The best things about my stay were the location, the price and Victor's communication.
However, as others have mentioned - the bed in one of the rooms is not usable. It's an old spring mattress that has zero support. You sit or lay on it and it sinks to the bed frame. I want to stress that I am not exaggerating. My poor dad slept on it and woke up with terrible back pain. I don't know why my dad didn't tell me but once he did, I told him to sleep in the other room I had used and I slept on the couch. I didn't pull out the sofa bed, just slept on it regular. We were both fine after we made this switch. We didn't make a fuss while we stayed because we had rented a couple nights at the beginning of our travels and had booked a couple more nights at the end of our trip. So know we were returning, it did not seem worth it. We just made due.
The toilet barely works. You have to flush over and over again before the toilet will successfully complete a flush - regardless of what is being flushed.
The internet is very weak.
I thought it was strange that all information for this rental states an 11am checkout time yet the day before departure we received a courtesy text stating departure was 10am. It didn't matter to us because we were leaving earlier anyway - but I can understand that other would find this frustrating and inconvenient.
Once you enter the building from the street - the common areas of the building are extremely run down. Once you enter the actual apartment (flat) it looks like the photos but definitely a cheap/budget renovation.
The location was great for what we needed. It was safe. Heat worked well - it was cold. The place was clean but amenities were extremely sparse. Typically when I have used AirBNB I feel like I am taking care of someone's home. In this case we felt like we were in a low rent hostel.
I would say if the price was right, it's worth the stay. While both mattresses in the rooms were in poor condition, one of them was completely unusable. Thankfully I was small enough to sleep comfortably on the couch. Better wifi should be installed.
