We loved the flat. The interior is very pretty and you feel very welcome in this flat. When it rained we could easily entertain ourself by all the books, games and Netflix. When it is nice weather you can play table tennis downstairs or enjoy the view from the balcony.
If you are having worries about sleeping on the couch , don't.
It is the most comfortable couch in the world and you will sleep perfectly on it.
Josh was a great host! He answered every question we had immediately by text.
