We had to unexpectedly spend a day in Cluj, and the hotel we usually stay at was booked full. We were happy to find a room available at the Seven Hotel (music festival in town). The rooms are somewhat dated and furnishing worn, but clean. Breakfast (very good), and Wifi included (good), and also included air conditioning (good- most hotels charge extra for air conditioning) . Near the train station (1 km), and city center (2 km). This hotel is an excellent value for the money, if you are a thrifty traveller. Taxi from the Cluj airport to the hotel will cost you about 35 RON ($9 USD).
Staff is very helpful, and the front desk speaks English.
I agree with others: comfortable, good location, and excellent value.
