Hi Marine, The apartment is exactly as advertised and does not state that the sofa is a sofa bed. There was also an Aerobed in the apartment for your use if you found the sofa uncomfortable. The blind works well but if you had a problem with it or any other problem with anything not working in the apartment you should have called the caretaker who will fix or replace anything immediately. There are sufficient dishes for three people, it's a small kitchen and fully equipped for cooking but most people eat out. If you were requiring more dishes, they can be supplied. Again, the caretaker could have helped you out if you just let him know.
I hope you still managed to enjoy your stay.
