It is not a full service Marriot like others I am used it but this information is not anywhere to be found on the website so there is not a lounge nor room service. Although the shuttle is free but there is no set schedule at all so you could be going to the airport more than an hour earlier than when you need to be there. There are very few places that you could walk to eat.
The Residence at Marriot is connected to this one and they offer free breakfast, but this one doesn't.
The staff is friendly and helpful enough.
