It's located on the first floor of the airport, so it's fairly convenient.

They won't give you the car even one minute before 7 AM, even though staff are already inside.

I was two and a half hours late to pick up the car and was told the vehicle was no longer available. Communication with customer service was unhelpful (they said it was my fault for not reading the rental terms). I had to negotiate with the car rental company myself, and they finally resolved it (originally rented at Terminal 2, but they contacted Terminal 1 where a car was available).

Excellent, everything was great

Pretty good. The overall appearance and reception were nice.
