The hotel is great and I would say it is the best option if you have an early flight through CRL airport. The rooms are in perfect conditions, only the bathroom might require a better ventilation system.
However, it should be noted that there is not much to do around the hotel other than enjoying some good time at the restaurant/bar downstairs, unless you want to have some peaceful time outside the city’s noise!
With regards to transportation to the airport, you will need to arrange it at the reception while you checking in for 5 EUR.
