We had a lovely stay, it is a superb apartment, newly and well furnished. Cleen, bright and functional.
However, it seems like it is not quite finished. Picture is on the floor, missing lists, and when you turn on the washing machine, the kitchen sink gets full of water. And the water container is apprently very small. There was not even enough hot water to fill half a bath, even if we had not used hot water all day.
We were five person, which is maximum. There was only sleeping arrangements made ready for four person, and the fifth person had to sleep on the floor on an air mattress, which we had to fill air into. There were only four glasses, four mugs, etc. So we would say that the maximum is four people.
There were two double beds which were VERY worn, they didn't support the back at all, one could clearly feel the springs. There was not a duvet per person, but only a duvet per double bed, so you had to share. And the fifth person had to use a blanket/quilt.
But overall a good stay, when we arrived we had some questions, and they were quickly answered, we asked if we could get an extra key, so we had two, and it was no problem.
We would recommend this apartment, however to a maximum of four people and only if you don't have back problems.
