I am a longtime Airbnb customer, and I am sorry to say that this was the worst Airbnb experience I've had. To start off, we had no wifi during any point in our stay, and it is unclear what our host did to try to fix that problem (she kept saying she hoped it would start working soon, but it never did). There was also not hot water on the last day of our stay; apparently this has happened before and there's a process for resetting the tank, but by the time we heard back about that we had already left for the airport.
It was also extremely hot in the apartment, despite air conditioning being mentioned a few places on her page and air coolers specifically listed in the extensive list of house rules. The air coolers were there, but they did not work - we had them on all night and the temperature actually went up (from 28 to 30 C/86F). The temperature was better with the windows open, but there is a constant stream of cigarette smoke coming into the apartment both from the street below and the courtyard outside the kitchen window, which is not only unhealthy but will result in a 100 Euro fine from your host. So, we could only leave them open for a little bit at a time.
We reached out to Anastasie about the coolers; she told us we must be using them wrong (we weren't) and that she hoped they'd start working soon. Again, while wishing us well, she didn't seem very interested in actually solving the problem. We asked for a discounted rate given the issues we dealt with, and she was very resistant, eventually conceding to a very small discount (which we spent the last night of our trip fighting for). I've never experienced such inadequate customer service from any other Airbnb host.
After all of this, she still reached out to try to get me to give her a 5-star review. I would never do that if I knew my guest had a difficult experience; it added insult to injury. Overall, it seemed like she cared much more about rules, fines, and growing her business than providing a pleasant stay for her guests.
