Overall very good experience.
Nice location, newly renovated place as the description.
Easy communication with the owner.
Two things FYI.
Firstly, it's not stroller friendly. Steep and narrow stairs make it hard to bring the stroller up and down.
Secondly, the curtains are thin and not light blackout. If you are not a good sleeper, you will definitely be awaken by sunshine. Also you can always hear the noise on the street.
It may not that kids friendly, but I highly recommend this place to other travelers.
