In general, we had a good experience. However, you should be aware that finding a parking for your car will be a little bit challenging. Moreover, there was no towel and no bed linen included in the price. It seems that you should pay extra for that which I dont know who much.
The apartment is good enough for 6 persons. You should bring soap, shampoo and all the essential hygiene with you.
Howevr, as I said if you are not a picky and sensitive person, you will have a fairly good stay in this apartment.
