I think what you have written is not true. I am still sorry for the inconvenience during your stay.
The door in the bathroom is not there because it is an acces for dissabled people with wheelchair.
The matrasses are top quality matrasses made in Florence from a private manufactury.
The floor of the bathroom has been renovated last winter.
And the floor get wet because its a bathroom for disabled people and there are no steps｡
About the musquitos there is an instruction on the wall where is written what you have to do.Was easy just ask the next day a new tablet or use a mosquito repellent.
There is no kitchen in the hostel, we have plates, cups, fridge, microwave, water cookers and a vending machine. We are sorry for the knives. I think a backpacker that goes in a hostel have to be flexible and uses his personal tools or choose a hotel next time.
We are located in a very old building so sometimes it can be more loud ,this is also Italy.
