I stayed there last July for a night and I have to say I was sooo thankful to be checking out. We had a bad experience and I did not feel that the hotel was appropriate for a family with young kids. Now, for young adults it would probably be just fine considering the pool bar that kinda get rowdy at night! The hotel looks ok as far as appearance goes,but whatever you do, make sure you ask for a room on the side opposite the freeway when you check in. The freeway side is extremely loud..think sleeping on an airstrip when a plane is taking off..that sort of loud. I went down to complain but they claimed they could not move me as they were booked solid. I will say the restaurant serves good food and is relatively cheap!
As far as walking, no it is not walking distance, but the ART shuttle does stop there. They are pretty cheap if I remember right. I am not sure if they have laundry facilities because I was only there for one night. I would suggest looking it up on tripadvisor to read the recent reviews. Either way, enjoy your trip!
