This is a very nice hotel with excellent reception staff and very clean rooms. Normally I would give it 5 stars, but there is no A/C in the rooms and, with temperatures in the mid-30s at the moment (36 yesterday), it was impossible to feel comfortable. In fact, it was difficult to breathe and sleep. This can be very distressing. We always carry a fan with us, but even this wasn't enough. For many people, the extreme heat in the rooms must be a health hazard. The fact that the prices at this modern hotel are quite high means it is unacceptable in this day and age that there are no A/Cs or air-cooling systems in the rooms. Not even fans. After the severe heat wave across Europe last year, with temperatures in the 40s, the hotel has had enough time to install a cooling system.
