The flat is rented out by an agency as other users already pointed out, nothing wrong with that... BUT they are very unfriendly and you have to calculate about 35€ for sheets and towels if you don´t bring your own (which is a pain via plane).

The good:
The flat itself is very nicely located and has a great terrace with a perfect view, it is spacious enough for two and a good place to stay.
The kitchen is well equipped.

The bad:
The flat was not very well cleaned, lots of foreign hair on the floor and the bed and a little ant-problem.
the bed is actually two single beds and they are quite hard and uncomfortable
the refigerator is very noisy so you will have to turn it off overnight if you have a light sleep.
