Beware of this hotel in summer! It was much too hot. Some facts: the chocolate they gave us melted in the room heat; the room temperature varied from 30 degrees to 27.5 but never went below that. The staff said the ecologically designed air conditioning system couldn't handle hot days. This is a 4-star hotel, not a cheap hostel, and that is not acceptable. We don't know if the hotel was full, but they never offered to move us to another room. Otherwise the staff was helpful and kind. The hotel has beautiful modern design and everything is well constructed. There is no cheap IKEA furniture. But a lot of the "good" design is not practical. The wooden bed platforms have low and sharp edges to bump. It is impossible to keep water inside the shower with no door. Some of the light switches are hard to find. This can be a good hotel, but beware in summer. Our experience was not restful.
