I stayed there for 2 weeks. Overall the stay was nice. The reception was very friendly although they did not speak much english. The free Wi-Fi was horrible, but you could buy a much much better connection for 5EUR per day, which was excellent.
The apartment it self was fine. The beds weren't the best but there were 2 AC in the apartment, along with the most basic kitchen equipment. I wished there would have been more things like knifes to cut with, cutting boards and things like that, but overall we managed.
Cleanliness was good although they don't provide you with soap, toilet brush or any kind of washing material for the kitchen.
