Katerina's place is incredibly good - you should stay there! I HIGHLY RECOMMEND.
We spend ONE MONTH there so believe me if anything would be bad, we likely know about that.
The place is very clean, cozy. The city center is only 30 mins slow walk away. And the panorama is amazing - yes, the same as you can see on the pictures. You can find some guides with great local tips in the flat, I would recommend to check it.
The kitchen is cozy and has any equipment that you need for (pans, glasses, etc).
The bed is really comfortable, the bathroom is absolutely fine. The whole flat is friendly and cozy :)
So long story short, you will be happy there!
