Great value for money, very central location with no overpaying for extra space, but still clean and very functional. Good for a solo traveler. Every necessity is there: clean bathroom with a big shower (just don't shut the water when using the shower, it takes some time to heat back up), a small but fully equipped kitchen area, a table and a bed.
There's even a balcony. It overlooks a street, so no super scenic views. There was some music outside very late at night, but it was far away and didn't bother me.
The host was very welcoming and responded immediately when there was a minor problem with the washing machine.
The spiral staircase is pretty steep and there's no elevator, if this is important for you.
