The hotel is not in the city centre it is actually close to the airport and approximately 20 minutes to the city centre. The area around the hotel is still developing, there are some offices and a big shopping mall only two minutes away.The hotel offers a free shuttle bus service from the airport to the hotel and vice versa. It comes every 30 minutes in one of the stands outside the airport. I had to ask a very nice gentleman who pointed me to the right direction however I took a photo for you so you find it faster than I did.
Once you exit from Arrivals look for the Hotel Shuttle sign or the Information Desk, you need to take the exit next to the Information Desk and then just look for the third stop as shown in the photo below. The shuttle should arrive promptly and it has the Crown Plaza Logo so it is hard to miss it.
