It was okay.
The distance from the flat to the City Center wasn't even a problem for us.
We had a problem with the cleanliness. Our room was clean but the bathroom and the kitchen were in a dirty condition. Of course they were used by other people as well but the look of the bathroom on our arrival was so nasty, we would have prefered to use a public bathroom instead of this mess. It was cleaned on the next day then it was fine.
When you stay here you have to be aware, that you share those rooms with others and you have to be insensitive about it.
