We stayed for 10 days in the flat. It was a nice time, the place of the flat is very central and quiet at night.
The first impression was that the windows in reality are much smaller than in the photos. However it was ok, and it was nice to have a good view of the city.
It was nice to have heating air conditioners (it was the beginning of april, so pretty cold at night). The floor are tiled, so you can bring your own houseshoes if you want to have warm feet.
We found only one dishwashing tablet for our stay, so we had to buy the whole package. This was a little irritating.
We were also missing spice, sugar, coffee in the kitchen, there was only one sharper knife for cooking. Would have been nice to have a vacuum cleaner, and a blanket for colder evenings or going out to the beach. So be prepared if you need those :)
