Since my flight was leaving at 6 in the morning, I decided to stay here for the night. The location is perfect to catch an early flight, as it's literally across the road from the terminal.
Staff was friendly and professional, the check in and check out went smooth.
The room itself was clean, modern and comfortable. All facilities worked as intended, although the temperature control probably needed a bit of a check as it was quite warm in the room, no matter what. There were sufficient power outlets to charge any equipment.
Despite being a stone's throw from the runway, noise isolation measures have been taken so that you'll actually get some sleep.
If I have a red eye flight from Cluj again in the future, then I'll definitely consider staying here again.
One tip about the airport: despite this hotel being right next to it, the facilities at the airport are limited and lacking. So leave on time. Prepare for a 45 minute security line in the morning, for example.
