My stay was 12 weeks. I would not recommend for a long term stay, but short term might be doable, if you can tolerate what I describe.
The major problem was that she created issues about money, even though I paid everything through Airbnb. I reserved this months in advance for work travel. I heard nothing after her accepting my reservation. I contacted her again a week before, to follow up, and she said she'd send me all the information. Then a couple days before my arrival, she suddenly asked me to cancel the later portions of my reservation and pay outside of airbnb, claiming she wasn't getting enough money, even though she had months to see her total. Being new to airbnb, I tried to work with her. I cancelled part of it but said I couldn't pay more than I had agreed. She became annoyed when I apparently didn't cancel what she wanted, saying I "didn't listen to her", and it was not her fault if airbnb charged me fees, suggesting it didn't matter if I ended up paying more with this new arrangement that was entirely her idea. After a lot of back and forth, I finally told her it needed to all be through Airbnb, and so she said to change it back, so I did, and she accepted the change.
A week before I was to leave, she began claiming airbnb did not give her enough money for my last payment, and asked how much I paid. I told her what I remembered, but wasn't sure what that was in euros. It was what the plan had been for 6 months at this point. She started saying how she had to pay for electricity and didn't have a job and complained that I sometimes used a fan (the room is much hotter than where she sleeps). Electricity is included, and I was rarely there on weekends, rarely used the lights or kitchen, and was gone for a two-week holiday that she was still paid for.
I decided to leave early, even though I paid for the whole time, sent her a message letting her know where the keys were and explaining it. She denied doing more than "just checking what the last payment was", despite messages right above from when she complained about money in the beginning.
The accommodations also should be explained better. She sleeps in the living space, which contains the kitchen. I rented the bedroom. The bed (futon) is not comfortable. She kept saying she would put a different bed in (even though I never complained), but never did. There is no place to hang clothes. I bought hangers and hung them off the heater. Bathroom is shared, with only a bathtub and removable showerhead, no curtain. No towels provided. There was a small stove and toaster oven, no microwave. The refrigerator was small and crowded. This isn't necessarily bad, but is good to know as alot of standard things aren't available.
