I do not recommend this place at all. Let me tell you about this nightmare.
The place has a quite central location, close to the old town and main touristic areas. The view from the window is nice, directly to the New Town Hall, and the acoustic and thermic isolation works perfectly fine. However, the sheets and blankets were not the right sizes for the bed, meaning that I had to sleep on a bare mattress. I talked immediately to Tatiana, the owner, but although she could have easily solved it, just by buying a new set of bedclothes, the situation ended up in eight days of sleeping on a bare mattress. Because of that reason, since there was no intention at all to fix the problem, I moved to another place. The place was not cleaned properly, under the bed there were plastic bottles and a lot of dust and some items of the previous guests I guess. The mattress itself looks quite worn and dirty, the same as the sofa. It is clear that the apartment requires just a bit more investment to improve to a 5-star place since the location and the apartment itself are great, but it does not have all that is on the list nor the quality one expects.
UPDATE (two weeks after check-out): I finally managed to move to another airbnb, after giving evidence about the problem. Airbnb support was quite efficient and I got a partial refund for the nights I did not stay.
It was clear that the shower and toilet had some issues from the first day. The water level in the shower could easily reach its edge if someone takes a long shower, but since I do not take long showers I decided to not complain about it. I thought that the important issue was the problem with the bed, and considering that Tatiana had difficulty handling this single problem I did not want to "overload" her with secondary issues. That was a terrible mistake! After two weeks, Tatiana, the owner, is asking me for a refund of 5000€ for repairs due to a blocked toilet and shower. I hoped Tatiana could invest in enhancing the experience for her guests but not at expense of their own money.
I write this review to prevent other guests from falling into these bad practices that seek to profit at their expense.
