This marriott is not in the old town, but I like the location better. You are right next to a metro that will get you anywhere in the city. The old town is very touristy, so it was nice to get out into the other areas. It is a big marriott and the service very nice, rooms nice and everything you would expect from a marriott.
We arrived at the airport and took the bus to the main terminal. WAIT a minute...why not just grab a cab? BECAUSE it is so easy and actually quicker to get into town on the bus. As you leave the luggage area there are machines in front of you where you buy a ticket that allows you metro and the bus to the main terminal station. We bought a 3 day pass for the two of us 36.00. You will take the metro so this is a good value. The hotel is a quick walk from the terminal. Loved this location
