This hotel recently changed hands and names, and many improvements were in process when I stayed, although they didn't interfere with my stay. The location (right off the main square), and the configuration (two floors of rooms around a pretty interior courtyard, which kept things quiet even on a main street) were great. Reception staff were superb. All of them seem to have been hired from a tourism/hospitality degree program at the local university, and they had clearly learned from a master. They all spoke English and they were uniformly efficient, pleasant and genuinely helpful in response to some unusual requests. One of them booked a return flight for me from Belgrade to Munich from the reception desk's computer and was very diligent about finding me the best price. Another helped me locate some old friends in a tiny Gypsy village 60 km out of Cluj, got me accurate directions there, and made me promise to call him if I wasn't back by midnight (concerned for my welfare, not a pickup:) ). The hotel restaurant is nothing fancy, but it was adequate, and the dining room was open from early morning to 10pm. The gates to the courtyard are closed at 10, so everyone is routed through the reception office, and the parking lot is gated and monitored, making this a very secure location for this solo female traveler. The room and bathroom were basic, but felt luxurious in their immaculate cleanliness, comfortable bed and linens, and the handy fridge. I stayed a few nights and found everything satisfactory.

My sister and I stayed one night here after a very long train journey. The staff were helpful in offering advice on how to get to the airport to pick up our hire car the next day, what we could expect to pay the cab driver etc. The room was comfortable and cool (no air con though) The outdoor courtyard area was being renovated and the staff were apologetic about this but it didn't bother us.
Basic outdated bathroom but it was clean and the water pressure was good.
Breakfast was the usual European cold cuts, cheeses, sweets etc.
Good for a city stopover if you need a place in town. Close to the older, nicer part of Cluj-Napoca (walking distance)
Wifi worked well.

We stayed one night at the Hotel Transilvania. The location was very good - easy to walk to the main areas and sights. We had a basic double room, so it was a little small. The rooms were very clean, though slightly run down. The wifi access worked well and there was free parking in a secure lot in the back. The staff was friendly. For the price this is a decent pick.
