That was one of my worst experiences! No A/C in warm summer, and the reception said only half the ventilation was working, which I honestly don't get. They offered a fan, but said I had to come down to reception to get it! No one to bring it in a hotel like that? When I was at reception, two hotel staff were just sitting there, not to mention the people they probably had for room service and stuff. Opening the window in a hotel room facing the train station wasn't an option either. Hotels, even hostels, with much cheaper prices offer better service. At least their ACs work in mid-summer, or if you need something, the staff doesn't tell you to come down and get it yourself.
