The location of the hotel is conveniently close to the airport.
Service at the reception desk was standard.
The room is quite standard, batthroom for this type of hotel is below standard. Positive is the sound isolation which is a requirement so close to the airport.
There are 2 main restaurants: a noisy "rustic" restaurant where smoking seems to be obligatory, and the international restaurant to which we escaped in view of the smoke; it is big and quite empty when we were there. However, we had an excellent meal and good service.

We decided to book a room having a flight at 6am. We checked in the evening before departure and enjoyed the small but cosy hotel's health club facility (free for guests). The rooms are basic but quite large and nice decorated. The view from the room is something that needs improvement but we did not come for the view. We had a good sleep in the comfortable beds although from time to time we could hear planes above. Still not an issue. The next morning we had a mini coach waiting for us (every hour from 4am, also free for guests, beat that!) and we arrived smoothly at the airport in about 10 minutes. Overall, not a bad experience, this airport hotel is what is needed for an early flight.

We got put up here when our British Airways flight was cancelled, they provide a free hourly shuttle bus to the airport which is only a short drive away.

The rooms were fine, the on site restaurant gave decent enough food and the staff were friendly. The biggest surprise how ever was the strip bar in the basement!

Decor leaves a bit to be desired but the point of this hotel is it's early airport shuttle, be warned how ever breakfast is not served until around 6.30.

I stayed at Rin Otopeni for my last night in Romania, before catching an early morning flight out of Otopeni. I reserved online and the affordable rate included a free airport transfer the next morning. Overall it was the perfect "airport hotel" to suit my needs. The room was simple and the bathroom was beginning to show its age, but the bed was THE best bed I've ever slept in! The mattress was perfect and the pillows were out-of-this-world. When I woke up in the morning I seriously considered missing my 7:00 am flight to spend more time in the bed!

The hotel also has a swimming pool, sauna and fitness center, but I arrived too late to use the facilities. Airport transfers run every thirty minutes (I think) from 5:00 am. Book the night before or when you arrive- the shuttle was totally when I took it. I had a quick dessert in the restaurant (the papanasi were great!) and noticed the menu looked good.

Between the facilities, the food and THE BED, I wish I'd arrived earlier and stayed a bit longer!
